My first two were 12 months and 5 days apart. I was so upset that my cute little toddler would be left out or jealous and sometimes he was and sometimes he wasn't. He loved his brother and it's all in how you present the baby and how you continue to relate to the older child. It's a big job and many sleepless nights and lots of baths and feedings but it's so worth it. You'll get to hold a little baby again and then also play with a toddler and see them learn to love each other. I had a couple of kids 14 months apart and some 19 months and so on and it is work but yet you will get through it. Try not to think too much ahead of things until they happen and it won't seem so overwhelming.
