Must Knows

  • Let yourself feel
  • Give yourself permission to break routine
  • Know you don’t have to throw a big birthday

As you approach your baby's first birthday, remember to let yourself feel during this emotional time. Where did the past year go? How did it go by so fast? How on earth was it so hard and so wonderful all at the same time? These are the questions that all parents ask themselves, so we completely get it.

The upcoming milestone of your baby’s first birthday can bring up a lot of emotions, so take some time this month to work through them. Whether you need to cry, sob into your baby’s newborn clothes that you’ve packed away, or create a 100-page photo book to commemorate your baby’s first year, do what you need to do. That way, when the first birthday finally hits, you’ll be ready to celebrate with a smile on your face.

It’s been a long 11 months of you laying down the foundation of routines, sleep schedules, and healthy habits for your little one, but this month, give yourself permission to shake it up. Take the day “off” and have an adventure for your little one—call a friend to meet up for breakfast, introduce your baby to the joy of splash pads or an indoor waterpark, and go with the flow even for one day.

Let’s be honest here—your baby has no idea what a birthday is and will have no idea if you don’t throw a huge, Pinterest-worthy party. So, if you don’t feel like you have the space, energy, capacity, or finances to throw a party for your baby’s first birthday, don’t worry about it! Make the birthday what you want, whether that’s an all-out bash or a simple family dinner with a store-bought cupcake.

Your Growing Baby

By 11 months old, most girls weigh 19.2 pounds and have a length of 28.7 inches, while most boys will weigh an average of 20.8 pounds and have a length of 29.3 inches.

One of the biggest development changes that happens as your baby approaches toddlerhood is that your infant will lose that chubby baby look and start to lean out. Walking takes a lot of calories and those cute little rolls will be replaced with more lean muscle to power your little one’s laps around the house. 

Developmental Milestones

Here are some of the physical and mental developments you can look for this month:


  • Crawls
  • Stands up unassisted
  • Walks and/or takes steps
  • Points or goes for items they want
  • Grabs finger foods and feeds themselves
  • Babbles and imitates words
  • Waves “bye-bye”
  • Starts to say simple words like “Mama” and “Dada”
  • "Scooches" butt
  • Rolls from back to front and front to back
  • Can stack play items, cups, or bowls


  • Sees colors well now
  • Develops specific preferences for tastes and textures
  • Shows curiosity and explores how things work
  • Expresses separation anxiety
  • Shows personality traits
  • Attaches meaning to words, like going to get shoes when you say you're going “bye-bye”
  • Understands simple one-word phrases or requests
  • Loves music and dancing
  • Mimics animal sounds

When to Be Concerned

If your little one has not attempted crawling, is not able to sit up on their own, and doesn’t seem to respond to you or try to interact with you, be sure to speak to your child’s pediatrician.

A Tip From Verywell

Talk to your doctor if your baby hasn't attempted crawling or isn't able to sit up on their own.

A Day in the Life

At 11 months old, your baby will be active, full of energy, and ready to explore the world around them. Your daily schedule with your baby at home or in daycare might look like this:

  • 7 a.m.—Awake time, morning nursing session or bottle
  • 8 a.m.—Breakfast such as cut up fruit, yogurt, or scrambled eggs
  • 10 a.m.—Morning nap
  • 12:30 p.m.—Lunch
  • 2 p.m.—Afternoon nap
  • 5:30 p.m.—Dinner and playtime
  • 7 p.m.—Bedtime routine begins
  • 7:30 p.m.—Lights out for bedtime

Baby Care Basics

As babies this age are learning to walk, some babies will walk on their tippy-toes. Although your little ballerina may look adorable, you might wonder if that tippy-toe walk can be harmful in the long run.

Fortunately, most of the time, toe walking is completely normal and your baby will eventually stop on their own. Until then, you can simply encourage your toddler’s first steps and allow them to figure out how to walk at their own pace.

As your baby learns to walk more and more confidently around the home and in the world, you can support your baby’s new skills by allowing them to walk barefoot as much as possible. While you probably don’t want to let your baby run around the park barefoot, when you’re at home, let your baby’s feet be bare without socks or shoes to allow them the best environment to develop their walking skills.

Feeding & Nutrition

Along with 16–20 ounces of breast milk or formula, your soon-to-be toddler’s diet should include plenty of fresh food that incorporates:

However, you should still avoid common choking hazards, such as nuts, popcorn, hot dogs, and whole grapes.

Next month, you might introduce cow’s milk or a different milk alternative, but this month, continue to offer fresh or frozen thawed breast milk or formula for your little one’s snacks and meals. You can also give your 11-month-old water with meals, but avoid giving juice unless it has been recommended by a pediatrician for a medical reason, such as constipation.

If your little one goes to bed early or takes an hour to eat a simple meal, you may wonder if you should even bother with family mealtimes. However, family mealtimes have been shown to be associated with positive traits, such as lower BMIs and positive psychological effects in children, so start establishing healthy habits now with family mealtime.

However, if family mealtime is just not possible for you right now, don’t worry—do what works for you and focus on embracing what works for you as a family in each stage and season. No matter if you eat together as a family, mealtime is a great way to model the table manners you want for your children, such as:

  • Using silverware
  • Drinking from a cup or sippy cup
  • Trying new foods together

At this age, your baby will start to show a preference for certain foods and may grimace or make an “ick” face when you introduce new foods to them, but don’t give up. Keep introducing healthy foods first and try to make trying new foods a fun adventure to explore together.

Eating finger foods and making messes are especially fun for your little ones, so let them get as messy as they want during mealtime. It’s important to keep food fun for kids at this age, so never force them to eat and let them lead the way—while still providing them with healthy and nutritious options.

Even though your baby is about to turn 1, you can still continue to breastfeed for as long as you want and as long as mutually comfortable for you and your baby. Should you happen to conceive or may even be pregnant again already, you can still continue your breastfeeding journey through pregnancy as well, if you would like.

You may notice changes, such as more sensitive nipples or even your baby rejecting your milk because it tastes different. But there is no medical reason to stop breastfeeding through pregnancy. Be sure to take a prenatal vitamin and eat a healthy, balanced diet to ensure you are able to maintain your milk and the nourishment both of your babies need.


By 11 months, your little one should be sleeping well through the night and may be transitioning out of a morning and afternoon nap to just one longer afternoon nap. Even if your baby is starting to fight it, they still need that afternoon nap, so stay consistent with it. But keep in mind that life isn’t perfect and sometimes, a nap gets missed and it’s not going to ruin your baby’s sleep forever.

Some babies may go through a slight sleep regression at 11 months too, possibly related to a growth spurt, or just a transition period as your little one learns to walk and adjusts to a more active lifestyle. Stay consistent and offer comfort, but also space for your baby to learn to put themselves back down to sleep on their own.

Health & Safety

Although your baby is approaching toddlerhood, they will still be getting baby teeth throughout the upcoming months. A baby’s first teeth usually start to come in around 6 months and will continue through childhood.

Between 10 and 13 months, your baby’s central and lateral incisors will start erupting on both the upper and lower gums. Keep your baby comfortable with a weight-appropriate dose of an NSAID, like ibuprofen or Motrin, teething toys, or a wet, cool washcloth to soothe their gums.

One of the most important things you can do this month is to approach babyproofing your home through the eyes of your new climber. All babies are different, of course, and some may be more adventurous and curious than others, but at 11 months old, most babies are more capable of climbing than you realize. Especially when they see something they want that is out of reach, babies are determined creatures who will find a way to get to it.

Unfortunately, many babies can get injured as a result of climbing or getting tangled in a window blind cord, so look around your house and do your best to childproof against your little one’s new climbing skills by:

  • Installing locks, even on upper cabinets and cupboards
  • Removing all window blind cords from your house
  • Lowering crib mattresses
  • Making sure furniture is not near windows
