I know how you feel. I struggled and struggled to have a second child, and part of what I was struggling with (along with the physical trials, doing IVF and all) was the concern about whether it was in fact the right idea even to be trying. Our son is sweet and content, and life not impossibly hard taking care of him, and the idea of a new sibling is entirely unknown territory. At least you have other kids and know what it does to add more. :) I don't have any answers for you, but if you're unsure and your husband is only wanting another one in a 'sort of' way, gee, I wouldn't be in a hurry.
