Second thoughts about second baby.

Reade
Can anybody else relate to having seconds thoughts on being a mom for the second time? At times i think it will be good, my son likes to help and I'll have a little eye for when i pee real fast and what not lol. But then the negative side of my brain tells me, how am i going to have two kids a toddler, newborn, go to school and keep my house clean and give my husband his attention? I don't have a very big support team other then my husband but he works soooo much while I'm able to stay home and i don't want to burden him to much.
