Can that actually hurt the babies? Or her?

Okay so legit and probably very stupid question. I’m friends with my brothers ex girlfriend and she’s 35 weeks pregnant with their twins and I was laying down with her and her 1 year old and her one year old rolled over and kicked the absolute crap out of her stomach and her stomach tightened up and the twins responded to that and started kicking the crap out of her too.

Can that actually hurt them/her? I felt so bad because she was laying on me and I didn’t think to catch her and keep her from aiming her legs right into her moms pregnant belly
