Unsolicited parenting advice 🙄

How do y’all handle this? I feel like everyone wants to tell me how to be a mom. My own mom understands perfectly that I like doing this on my own. Other relatives want to tell me I’m doing something wrong or I should do something else instead.

My baby is almost 11 months & I was asked by a relative how much formula I give her. When I told her between 7-8 ounces 4x a day, she made a face and said “not 10 ounces?” I explained that since she started liking food more she doesn’t finish her bottle so give her what I see she actually finishes. And then she began telling me about her 3 kids and how much they had.

I try to keep it peaceful with family but sometimes I want to scream because I feel like they think I’m stupid and don’t know how to be a mother. I am closer to 30 than I am 20. I’ve taken care of myself since I was 18. These little comments just bother me.
