I have 2 under 2. They're 17 months apart. I'm working on 3 under 3, and my second and third will be 11 months apart. I'm not worried at all, though. I think 2 under 2 is an absolute breeze. I made my older child a part of the pregnancy. I'd lay him on my belly when baby was able to be felt from the outside and let him feel the baby, I took him to ultrasounds, I'd get him all excited about how it's his baby, too... Now, he takes WONDERFUL care of his little brother. He's not even 2 yet, but he can change a diaper, can feed the baby a bottle or spoon feed, he shares toys and snacks, sings to his baby brother, etc. It's great! He makes it very easy for me. I'll be doing all the same things for both of my kids, with this baby, but my toddler is already prepared, and he's excited to have a baby on the way already.
