Being married to someone is hard enough; add kids to the mix and you multiply the joy — and, yes, the challenges.

Even the easiest kids add new things for a couple to argue about.

What happens if the child isn't "easy" — like a kid with special needs.

I chatted with Brazen Careerist Penelope Trunk who blogs honestly about her sons, one of whom has Asperger's (so does she). She says "It's nearly impossible to keep a marriage together with a special needs kid."

Do you agree?
