Baby doesn’t want me 😫

I’m 21 weeks pregnant and it seems once I found out I was having a girl, my son doesn’t want me. My 13 month old cries for dadda and I can’t calm him down. My hormones make it 100x worse and I feel like such a failure. I just want my mamas boy back. Does he not like that my belly is in the way when I hold him? I just sit and cry sometimes. Dadda wasn’t the one up with you for 6 months, I did it all, and I still do most of it! (Husband is out of town a lot)
