18 weeks 3 days. Baby moving like crazyyyy!

This is my fourth pregnancy. My first time with a posterior placenta. It is so strange and awkward feeling my little woman as much as I do! Anyone else a little creeped out by this ? It is a beautiful thing but she does not stop! It’s like nails on chalk board feeling ? I never felt my others like this at all!! I hardly felt movement . Sometimes I’ll have an outburst like oooh or make a noise because I’m so startled by it . When have your spouses started to feel movements ? I don’t remember this at all with my others . Baby brain I guess !
