CRAZY Baby Movements...

Crystal • Mother of an amazing daughter (Jan. '16)... and an amazing son (Oct. '17). Two under 2 💗
Okay, I'm 31 weeks. Sometimes she moves so much, so fast, and so crazy in my belly....it feels like a volcano is erupting inside me. 
Does this happen to anyone else? She will do it for about 2-4 minutes straight.
