I'm 24 weeks and I get variations between the kicks and the rolls. The rolls are definitely the most funny feeling, but I love every one of them ...let's see if I'm saying that in a couple months! lol
Definately normal. I'm on my third child. I'm 30 weeks pregnant and he is beating my insides up. Your baby has just gotten bigger and iis having it a good time rolling around in there. I know what it feels like and it can get painful. Hang in there. U don't have much longer to go.
Those are probably her elbows/knees or her head/butt. How you can tell is that the elbows and knees will be connected to a long soft part (leg or arm) and will be smaller and bonier. To tell the diff. between the head and butt--- if you push on the butt, the baby's entire body will shift with that movement. But if you push on the head, baby will most likely move and then push back.
So yes, it's a normal feeling! It's just her body parts because she's filling out the womb and has nowhere else to hide.
