Husband woes?

I have a 2yr old, a 1yr old and another on the way in Sept. I am in danger of going into preterm labor and was told by my Dr. to take it easy. My 2yr old just started daycare. This means I have to get up, feed the kids, make make my husband breakfast, get my daughter dressed and ready to go by 8:00am.Now mind you my husband stays in bed until 7:40 am while I am doing all of this...then has the nerve to ask me to iron his clothes for work. He doesn't understand why I am angry about all of this. how can I make him "get it"? NICELY! He turns into a mute when I start to yell.
