Hi H.,
You sound alot like me. I had my second child when the first was about 18 months old or so. It is difficult, so just keep that in mind. You did not mention wether you are married or have a partner. I will assume you do. My suggestion is to each one of you spend some one on one time with each child, so that the older one doesn't feel neglected. It is easy to do with a new baby, because we feel that they need us so much more. But, in reality, the older child needs you just as much if not more than the baby right now. His whole entire world has changed significantly. At this age, he is going through so much: starting to feel a little independent but also still very dependent, testing the parameters of his world, and testing to see what you will let him get away with (or what is acceptable in your household). With my son, we did special things with just him: Dad took him to breakfast on Saturday mornings while I stayed with the baby. I took him to the playground while dad was with his little sister, etc. Again, it is difficult at first. Also, I think it is good to let him help with his younger sibling, hold a bottle, bring a book to read to both, etc. I don't know if I have the right answer for you, but it does get easier. Mine are now almost 2 and 3 1/2, and they get along pretty well for the most part. We still have our times when I think I'm going to go CRAZY, but overall, I really enjoy being mommy to two wonderful kids! Good luck, and hang in there! J.
