I went and got a jumperoo to hang in the doorway, because Felix is STILL not into tummy time and I'm trying to get him off his back. (Seriously, the poor thing is sporting the most severe mullet ever - he's rubbed off almost all the hair everywhere except his little duck tail in the back...) Anyway - the jumperoo is for babies 4 months and over, so he's just about there, but it's comically large for him. I shoved a blanket in there to keep him from going completely sideways, and he seemed to enjoy himself! Although, he's not so much jumping in it as just twirling. It's still cute.
