Hubby not supportive

I'm 12 weeks pregnant with our 2nd child.... First time around was a breeze but with this second pregnancy, I've had really bad morning sickness and all I want to do is lay down and do nothing..... My husband just gets mad and annoyed because he doesn't like to be stuck in the house and gets stuck doing everything, as far as housework and taking care of our 4 year old.... We've argued a lot because of this..... Any suggestions/comments??
