Newborn with leg shakes

[cushionstar]

Hi my 6 week old Dd was born 39 weeks via c section. Occasionally throughout the day I've noticed her one leg quivers and sometimes her bottom lip quivers too! Literally lasts seconds.
I never had this with my first born someone said it could be down to low blood sugar.
I will be seeing my Gp but just wondered if anyone else baby had this? Thanks xx

Both of mine had this. Immature nervous system developing the GP said and totally normal. But always best to get it checked! Trembling can be low blood sugar, but that presented quite differently in DD1 to the kind of quivering leg/lip.
