My baby prefers husband

I feel quite depressed as I've left a good job to be a stay home mum to care for my baby and I literally do everything for my baby yet when my husband comes home, my 3 month old smiles at him so brightly. I feel she isn't reciprocating to me. Not sure why? Is it because she doesn't like tummy time but I do it with her or i am the "bad guy" because I have to give her medication, put cream over her rash etc etc that she registered that I'm not someone she should love or smile at? Please don't judge. I'm really upset. #1stimemom #advicepls #pleasehelp
