Since Mariah’s room is rather limited when it comes to space, she’s still using her toddler bed (which actually is fine, she hasn’t outgrown it or anything). This means both the kids are still using baby mattresses. It’s kind of nice because most of the baby bedding I buy is unisex so they can swap back and forth. Mariah does have some girly ones that are strictly hers, but for the most part, they share.
