My wife has noticed that my 10 month old son sometimes starts to twitch his leg. It only lasts for a couple of seconds, and is infrequent enough that I have yet to witness it. She described it as uncontrolled shaking of the leg, and it seems to happen most frequently during feedings.
We had read that such shaking is normal in newborns, as it is part of their nervous system developing.
Is it normal that it continues to happen (albeit rarely) at 10 months?
