Fussy Babies and Shaking Movements

Babies make a lot of movements that are often mistaken for seizures, including having a quivering chin, trembling hands, and jerky arm movements. Fortunately, these types of movements are usually normal. Babies can have seizures, though, so if your baby is doing something that you think might be a seizure, you should discuss it with your pediatrician.

General ways that you can tell if a movement is normal or a seizure include:

• That the movement always occurs at a certain time, like when you change her diaper. You wouldn't expect a seizure to occur only when you change her diaper, so these shaking movements might be simply because she doesn't like her diaper being changed. Infantile spasms are more likely to occur when a baby is going to sleep or waking up, so that is an exception to a movement being normal even if it occurs at the same time each day.
• Whether or not you can stop the shaking or jerking. If an infant's arm is jerking and you can stop it by gently holding her arm, then it probably isn't a seizure. With a seizure, you would expect the jerking to continue as you held her arm.
• That your baby is otherwise healthy and growing and developing normally, which would also go against having seizures. Keep in mind that when a baby first begins having seizures, she may be otherwise fine, but over time, you would expect some other symptoms or problems with her development if she was having frequent seizures or spasms.

Keep in mind that some seizure disorders in young children can be rather subtle, like a simple head nod, lip smacking, or bicycling movements.

If your baby is gaining weight, it's not likely that her having low blood sugar is a cause of her symptoms. Is she having six or more wet soaking diapers and three to four loose, yellow stools each day? If so, and if she seems satisfied after feeding, then those would all be good signs that she is breastfeeding well.

There are other reasons besides not breastfeeding well to have a fussy baby, though. It could be that the mother is eating or drinking something that is disagreeing with her. Common suspects and things a breastfeeding mother might avoid include:

• Cow's milk and other dairy products
• Caffeine
• Chocolate
• Certain vegetables, like cabbage, onions, and broccoli
• Citrus fruits
• Certain medications

If you don't notice a difference in your baby's behavior after stopping these types of foods, slowly add them back in so that mom's diet isn't unnecessarily restricted.

Other conditions that could cause a breastfed baby to be fussy include having an overactive let-down reflex, and timing feedings, so that a baby is getting too much lactose-rich foremilk, and not the high fat hindmilk.

Lastly, a fussy baby who is 3 to 4 weeks old may simply be suffering from colic. Although no one knows the definite cause of colic, babies who are colicky usually have a regular fussy period each day that lasts for several hours. Colic typically begins when a baby is 2 to 3 weeks old, peaks at about 6 weeks, and is gone once an infant is 3 to 4 months old.
