Rawhide bones. This is what I find in the baby's room almost every day. I have no idea why. I pick them up, put them away, and they magically appear again by Alex's crib.
I've also found Maggie's tennis ball in the bouncy seat or swing while Alex is sleeping in these places.
I wonder if Maggie is giving presents to the baby. I also wonder if Maggie somehow believes that a 7 week old baby is going to play with her.
