Working from home with kids in the house is the worst! My son is just 13 months old and requires alot of attention so I had to literally send him to a sitter just so that I could get my hours in. Or sometimes, I would just wait for his dad to come home to keep him occupied while I work.
Carla, I actually wrote a post on my blog about childcare and the work at home mom. I believe childcare is definitely an option WAHMs should consider. You don't have to give up your role as the primary caregiver, just because you use childcare.
