He needs to stop playing games and being such a baby. If he doesn't like the way you do things, he can do it himself.
Tell him he is lucky he doesn't live with me, if he dare criticized my housekeeping, on top of working AND being pg (or complained he had to TELL me to do something) he would receive a frypan to the head.
There are things that need to be done to keep the house running, and TWO people to do it.

I hope you get this sorted before Liebling arrives, the last thing you want is his whining input when you are finding your way as a mother.
Being a new mum usually means dishes wait and washing stays on the line while you catch some sleep on the couch with your boob out.......
