My son was 2 years and 2 months when my baby girl was born. She's now 7 months old. We moved my son to the big bed about 2 months before the baby came. I thought getting him adjusted to a new bed before she came was important so that there wouldn't be too many changes once the baby was here. He seemed to do fine.
I made sure once the baby was here that I would say things like, "OK baby, it's Tyler's turn with Mommy," and I would make sure he knew when he was getting one on one attention with me. It's still hard sometimes. As soon as I'm feeding or changing the baby, Tyler demands my attention....he wants juice or a snack or a toy that's out of reach. So I try my best to meet all of his needs before I sit down to attend to the baby. He's old enough to learn that he can wait and share....even though it's hard.
I will say, though, that my little boy ADORES the baby. He's loved her from day one, so that's been a major blessing. The only difficult part for me has been his jealousy over my divided time.
