hstan15, you are not alone. Mine trembles too; legs, hands even lips. Doc said their muscles are developing so some baby have these symptoms which will usually improve over time. KKH has actually refered my boy to physiotherapy and last visit the doc said it could be sometimes baby cold or cannot control their movements hence jittery. But I look at my boy, he's definitely not cold . But since doc said it is ok, I also left it alone. Supposed to go for next review tomorrow but think I will cancel cos really could be a waste of time and $ just to go there, queue and wait to only hear the doc say 2-3 sentences which are really common sense one. My boy tremble much less now after about 1 month but still notice some trembling specially at his lips when he's drinking milk.hi. any baby with tremble legs occassionally? i saw that vivien (my baby) tremble legs a few days a day, is it normal??
