Sounds pretty normal to me...
Though if you're going back to work, then obviously somethings going to have to shift, as you can't work/do the rest of the childcare/do all the domestic crap.
As choosyfloosy suggested - you need to sit down and go over exactly what needs to be done - and split it all up:
Who's going to do the drop off at nursery
Who's doing the pick-up
What's the plan when dc are sick and can't go
Cooking
Laundry
Gardening
etc,
etc.
Couple of hints that can help,
(1)Try and have this conversation when you're both more in 'nice' mode rather than 'hate'. Be affectionate when DH comes home (even if you don't really mean it), get a takeaway, glass of wine, etc. These conversations work a lot better if you're in the right frame of mind. After sex helps.
(2)Once you've shared out the domestic stuff, make the stuff that's his responsibility, his responsibility. Try not to nag or micromanage.
(3)Fortunately, once you're back at work, the problem may reduce a bit as the attitude of "oh well, while you're sitting at home with the baby, you can clean the house" may drop off.
(4)Get time to yourself. looking after DC and doing the all the domestic stuff breaks anyone. Do whatever you have to do to get regular breaks.
Last, you might want to remind him that it's been statistically proven that men who do their fair share of housework and childcare get more loving.
(also - someone suggested the book "babyproofing your marriage"? read it - and get DH to. You may find some scary similarities to your story.)
