How do your babies sleep?

My daughter is a month old, she was sleeping in her swaddle every night in her bassinet.

Now. I’ve moved her to a pack n play, and she for some reason doesn’t want to be swaddled anymore.

I don’t put blankets in her pack n play, so her swaddle was keeping her warm at night..

how do you mamas keep your babies warm & still practice safe sleeping? It’s hot where we live so we have the ac at 73.

Without a blanket it’s a little too cool for a baby. Any tips?
