Well my opinion is that you should get to the baby making! I was pretty much in the same boat as you. I have a wild and crazy boy who is now 8 (9 in September), and a VERY strong willed and awesome dd who will be 6 in a few weeks, and a 17 month old ds2. I also have two dogs and a cat. People sometimes act like I'm crazy, and honestly I can't understand that attitude. Yes, my kids are high energy, but that is personality and it wouldn't change if I didn't have the baby (who is actually pretty mellow). Yes, there were times where I was shaking my head at myself over upsetting the status quo once again, but the baby really is a JOY. He is a sweet, wonderful bundle of joy. He isn't an easy baby, he is very, very attached and wants to nurse at least every hour, had to be held EVERY second as a baby, and it was still worth every bit of it. My older kids love having a baby, and it does make it much easier that he is so young, the other 2 are at school and he's home during the day like he is an only child. My husband is madly in love with him, and he was really on the fence about #3. You won't regret it for a minute, you might complain during the initial adjustment to a new baby, but once you get into the swing again it will be wonderful!
