Jamie- a schedule will be your best friend. I only have 2, mine are now 20 and 17. But when they were little, I was always harried and running ragged and working full-time didnt help. DH really wasnt alot of help eaither. I had to hear on Sat-Sun when I asked if he could get up with them and he would say" I'm tired I worked all week". Well hello so do I!. So we sat down with the kids and worked a schedule and what we did is we bought a timer and we would set it outside of my quiltroom door and set it for one hour and during that hour DH would watch the kids or if the kids needed anything they would go to him. When the timer when off then and only then could they bother mom.
many times when the kids wanted something, they would walk right past DH and come and knock on the bathroom door or where ever I was to ask me. I would say wheres dad..they would say"downstairs". I asked why didnt you ask Dad..reply--I dont know" it drove me nuts!
