Is this normal?!

Hi, I have a 16 week old baby who until recently slept perfectly well. However she has recently started lifting her legs right up, then slamming them down very hard. Whenever I check on her though her eyes are shut and she looks sound asleep whilst she is doing it!
Does anybody elses babies do this?! Is there any way I can stop it?!

mine does it - she's 1yo now and still does it repeatedly throughout the night (she's still in our room), really bloody loud

dd tends to do it just after she drops off to sleep. Occassionally as she is going to sleep.

Really irritating but I don't think you can stop it.

Yep, my ds does this too. He is usually building up to a big fart. The whole cot rattles. Not much you can do but agree, its very annoying.

Thanks for the replies! Its reassuring to know she isn't the only one!!
She does sometimes trump whilst doing it. I'm hoping it won't keep me awake as much when she goes into her own room at 6 months...
