"Baby always cold"

So my boyfriends grandma is in her 80's and whenever she comes into town she always talks crap about how we don't cover our baby up and that she's cold. She speaks Spanish and I don't, so she'll talk crap in Spanish. I tell her she's not cold but she doesn't listen. My baby is 2 months old, and it's summer, it's normally between 105-110 degrees everyday. It's hot! My daughter hates being hot and sweats easily and develops heat rashes on her face when she sweats. So when we go out I put her in just a onesie so she stays cool. If we go somewhere with cold air conditioning I bring a blanket just in case.

But it will be hot and my boyfriends grandma will say she's "cold" haha anyone else have this problem?
