Rachel • Mother to a beautiful boy 👶🏼💙
we have a rock and play for him to sleep in but since he's now here the incline freaks me out thinking he'll slip foward and his chin with go down. We decided to get a pack and play bc he doesn't mind sleeping flat on his back but he doesn't like that either. He would rather sleep with us. So now thinking about a co sleeper that we can put in the bed with us. But I don't want to keep buying all these things and not have it work. Anyone have any advice on what they use and how it's been working out?
