Duties of Staying at Home..

Abi

So, I've been having some problems with who does what around the house. My Hubby is the one working while I stay at home to take care of our 1yr old and soon to be Newborn. I was curious as to what a stay at home Mom is in charge of other than takin care of the kiddos? Dishes? Laundry? Cleaning the house? Do I do this every day without help because I'm a stay at home mom? What's he supposed to help with when he's the only one working or am I letting his work be his excuse to not help?
