My new born baby of 2.5 months wakes up at night with sudden jerk in body. Like he shakes a bit. Have you moms had this experience?

Yes it is common. Swaddling helps to prevent it

Yes it's normal.  U can swaddle the baby.

normally babies do such... yes you can swaddle... or else just keep a think blanket or cloth on her legs while sleeping so that she feels secured.. also you can roll a towel or blanket and keep beside her bums...

Its common...might be a nightmare.....They laugh and cry during sleep.
