My son doesn’t want me 😞

I had my babygirl 5 days ago and before that I was waiting on an induction that took longer than expected so my husbands family watched our 2 other kids. They stayed with them a total of 6 days and now my son (1) has been acting like he hates me. I know he’s only a baby but since I had the baby he wants nothing to do with me. He only wants his dad (my husband) he also isn’t interested in his new sister. Which I understand bc it’s all new to him and he probably feels overwhelmed but it makes me sad that he wants nothing to do with me. Idk what to do. I try to hold him and play with him but he will try to leave so he can go to his dad and my husband thinks it’s funny and to me it’s not. It makes me very sad. That was the longest I’ve been away from my kids and I feel bad. My oldest is 7 so she understands why but I feel like a horrible mom that my son doesn’t want me. Im crying even typing this bc I don’t know what to do. I feel so guilty letting him stay that long away from me and now it’s like I’m a stranger to him. Has anyone else dealt with a similar situation? 😞
