I feel bad

So my baby recently turned 2 months and my boyfriend’s family been pressuring me to let her spend the night with them and I just don’t feel comfortable with that. no matter how hard I try to explain it they just don’t get it and keep asking. I don’t want them to think I don’t trust them or I have something against them. I’m just not ready to be apart from my baby and now I feel like they hate me cause my boyfriend doesn’t really take up for me even though he feels the same. Can someone please tell me what I should do and how recently did you guys start letting your baby spend the night with relatives.
