A new baby to your other children? I have a 4 and 5 yo and both seem to have a BIG misconception about what it will be like having a baby. My oldest thinks that I can just go to the baby store and buy him his new baby sister (he won't accept anything but a sister baby) and my youngest seems to think that the new baby sister (also nothing but a sister baby for him) will be an instant playmate. Oh boy I'm in deep now
