So where do you guys let baby "hang out" when awake. Right now I only have the rock'n play but was thinking it may be time to get the activity mat since he's becoming more aware of his surroundings and wanting to look at things. He LOVES looking out the window at the trees, so usually I put the rock 'n play in front of the window if I'm not holding him. Where do your babies "play" right now? He'll be 1 month tomorrow, so I don't want him just laying in the rock 'n play every time I put him down to do something.
