I'm curious, because my husband and I were talking about this the other day. We consider our first son high needs, and even as an almost 4 year old, he is still very demanding and wants constant interaction. My younger son is laid back and goes with the flow. When DH and I talk about having a third, we wonder had our first son had a different personality if that would have changed how many children we want. We love our son of course, but he can be a handful. I would like to hear from others who have a high needs child and how that impacted how many children you decided to have.
