Pulling up and standing are fun and exciting milestones for babies. Standing is usually a prelude to cruising and walking and means that your baby is about to become a lot more mobile.

According to the Denver II Developmental Assessment milestone's chart, infants can usually:

  • Stand, holding on to things between 6 1/2 to 8 1/2 months
  • Pull to a standing position between 8 to 10 months
  • Stand for about 2 seconds between 9 to 11 1/2 months
  • Stand alone between 10 1/2 to 14 months

That isn't the range when all infants meet these milestones, though. It is simply when 25-90 percent of infants could stand, holding on or stand alone, etc. So, about 10 percent of toddlers could take a little longer and eventually meet the milestone a few weeks or months later.

Developmental Delays in Standing

Why isn't your baby standing yet? Especially if your child met most other developmental milestones a little later than usual, but did eventually catch up, then he just may need more time with this one too.

Some medical conditions that might cause a delay in standing or walking might include:

  • Cerebral palsy
  • Congenital orthopedic problems
  • Down syndrome
  • Muscular dystrophy

By 18 months, your pediatrician should make sure that your toddler can "sit, stand, and walk independently."

Talk to your pediatricians or consider a referral to early childhood intervention (ECI) or a developmental specialist if you have concerns that your baby isn't standing on time or is a late walker.

What to Know About Standing

In addition to these tips, other things to know about standing include that:

  • Most younger infants are able to stand up with support and bear weight on their legs between 2 and 4 1/2 months, and no, it won't cause them to have bow-legs.
  • Most toddlers can walk backward between 13 and 17 months.
  • Most toddlers begin running and walking up steps at 14 months.
  • Toddlers with undiagnosed developmental hip dysplasia can probably stand and will likely learn to walk with a limp or waddling gait.
