Everyone has their own ideas about what makes up a perfect family. For you, four is right. For others, two is perfect. And for some, who I think are crazy, one or even none is right. It's up to you to figure out what you want in a family, don't listen to other people's negative opinions.I'm pregnant with my third right now and we're keeping our options open to have a fourth. I'm also a stay at home mom and I love it. It's the best job in the world. But, I know my kids can be crazy and things can be hectic, so we're going to see how we and our budget handle three kids first. But, I'm pretty sure we'll have a fourth.My daughter is almost 3 and my son is almost 17 months. They're 18 months apart. This baby will be about 20 months younger than my son. I love having my kids so close in age! They have been best friends since my son started sitting up and crawling, they are extremely adorable and they absolutely love each other. They're at the point where they're finally fighting over toys and things so there's a lot of screaming throughout the day but I like that they're learning how to handle sharing and those types of social situations early. And my kids are close to the same developmental stages and the gap will close more as they get older, making them closer. They play with the same toys and love doing the same things together.I didn't find that having "two in diapers" was a big deal at all. I don't think it was any more work than having an older child and a newborn would be. In fact, still being in the "baby stage" of things made it easier to get back into the swing of having a newborn. It's not like I really had to remember or learn anything new when I had another baby and I could reuse a lot of the gear that we had. Having them so close means I can use the same crib, car seats, etc. for all my kids before their expiration dates hit!
