From time to time I have Mommy hubris and one might even say I'm stubborn. So, I must ask, is this ridiculous for me to think I can accomplish?

I'm due with our fourth baby in December, it will be a RCS. I have a 5 year old, 3 year old, and 2 year old (well he'll be 2 when the fourth one comes), and I normally ask my mom to come help after the baby is born and I'm recovering from my csection. Well, my mom doesn't seem keen on coming this time, we don't have any family close and recently moved and don't have any friends. I keep telling my husband that I'll be fine with no help and he keeps thinking I'll tear my stitches and bleed out on the floor. I really think I can do this with no help. My only concern is getting the then two year old in and out of the crib and driving to doc appointments. But, I think I can figure that out. Am I being too stubborn and insane?
