Baby Fever!

[sprout18]

I'm afraid I am getting baby fever again! I have three boys who are all just about 18 months apart. Well my youngest is now 15 months and I'm thinking I want one more! One more child would mean a huge change though as we would need a bigger vehicle, another car seat and since we got rid of all our other baby stuff we would need lots of new things for the baby. I would really like to try for a girl but if the next child we had was a boy we wouldn't have anymore. 4 is definately my limit. Actually I might already be preggo which is what really got me thinking about this stuff. My dh doesn't really want another one I think because he thinks its going to cost so much but really it won't cost that much except for cloth diapers in a small size cause I bf. I don't know. Of course if we got preggo now that would mean 3 out of 4 kids would be August birthdays! Am I totally crazy?
