Crazy 15 month old with a little one on the way...

Brittanie ♎️ • Mother of 3. 💗💙💙

I have a 15 month old daughter, and I’m now 12 weeks pregnant. She’s a little bit too young to understand that mommy has another baby coming. My daughter constantly is crawling all over me like I’m a jungle gym, bouncing on me, running against me. She’s not being malicious, obviously, but she’s getting too big and I’m getting further along, I don’t want her to hurt her sibling. How do I get her to calm down around me?
