How are you other mamas keeping baby warm?

My daughter is 9 months and oh how I wish she could just use a blanket already!

We love in Florida so it’s not cold cold but at night it has been in the 50’s. She wears fleece pajamas and I changed her crib sheet to flannel and we keep the heat on a little but the heat doesn’t seem to be working on her side of the house in her room so the heat is pretty much not keeping her as warm as I want her to be.

Thinking about maybe putting a onesie and socks under her fleece pajamas.

How are you other mamas keeping your little one nice and warm at night?
