C.S.
I don't know that I would try just yet. It seems like a lot for your son to adjust to. I have three kids. The first was 2 1/2 when my second came. She didn't show signs of jealousy until about 3-4 months. There may be some jealousy coming and I would be careful about changing too much at once. Especially with you going back to work soon. I also worried about the older one trying to help and throwing a blanket or stuffed animal in the crib. I didn't want to risk the blanket acidentally getting over the baby's face. When we had a third child we started to plan for my two oldest sharing a room. They are 2 and 4. It's only been two nights so far that they've tried. Honestly it's been terrible, but I hear it takes about a week or two to adjust.
