What age did you stop dressing your baby exclusively in footies/onesies?

HI! What age did you start dressing your baby in "outfits" vs. footies, during the day? Our little one is two months old and I love dressing her in footies... full-on outfits (tops and bottoms etc.) feels much harder to manage with how chilly it is out, and all the diaper changes, etc.

But occasionally I worry we're, like, doing the equivalent of dressing her in pajamas all day?
