Piercing baby girl's ears

She says it everytime we go over she's been saying once my baby is 40 days old were gonna go . It's like um excuse me but that's my child so you need to butt out . Like seriously , also what gets me mad is when she says that my husband asks her " when are we gonna take her " but he never talks to me about it. Plus I don't like the fact that my MIL and my husbands family think they can just invite themselves especially my MIL and SIL -.- they already ruined my birth by being there after I told the nurse to not let them in. I feel like piercing babys ears , taking them to the zoo, disneyland etc is something that should be experienced with just the babies mom and dad (if they have any siblings then with their siblings as well) NOT with your husband's family .
