Why does my baby squirm so much?

Could be wormy!: While possible it is not likely that your baby has pinworms! most squirmy infants are attempting to reposition themselves into a more comfortable posture; or, for the older baby, this may signal his wanting to explore his ever expanding world. Many newborns squirm craving comfort in being snugly swaddled; others wiggle to indicate discomfort in a wet or dirty diaper or an emerging need to be fed.

Squirm: Maybe you are gripping too tight? Or maybe the baby is just learning to gain dexterity and simply is discovering its own body and how it works so it does it by squirming. Unless it is really abnormal and dangerous, then it is nothing to worry about. They do this until they can crawl. Just like they cry and scream until they can talk.
