You buy food that you like that doesn't give you indigestion - if he wants anything different, he buys and cooks it.
If he doesn't bring the laundry basket down, only your own and dd's clothes get washed.
No more lifting and carrying for him - next time he wants a freezer moving he can call up one of his mates.
The irony is that he may well turn into a doting daddy when dc2 puts in an appearance but by then the damage will be done - you'll never look at him in the same way again, and whatever love you feel for him will forever be tainted by memories of his childish behaviour at what should be an exciting time for you both.
If you can bring yourself to do it, tell him to sling his hook and come back when/if he grows up.
