Big brother to be

Telisia • Mommy of 👦🏾👶🏾
Since I've found out that I'm expecting, my son have been hugging up on on me since day 1. He'll always ask me can he rub on my belly (only 6 weeks). My spouse been in New York for 2 weeks now on work duty and I'm here in Florida 😒😔 My son is always asking can he lay down with me.   He'll only fall asleep with him rubbing my belly or him falling sleep on top of me. Oh ps he's 4 years old. Not complaining though it's just so overwhelming sometime. 
Who else experienced this before?
