There is no love lost between you, and I am not surprised.
I have a similar arrangement too, as my dh is only home for two hours a day between working and sleeping, enough time to eat, shower and read a story to the dc, so if your dh is doing the same then I can see why it is you that does most things at home for the moment.
That said, things change at the weekend. He cooks all meals, does all the beds, looks after dc and does all sorts of housework. He does not get to put his feet up and do nothing. We all work at the weekends, and we all rest at the weekends once everything is done together.
Try and carve out some time for a break from the dc every weekend maybe each of you have two hours off. Then you divide everything up, all the jobs. You have a young baby and toddler it is hard work, but you can make this work for both of you.
Every Saturday could be your night together, little ones in bed and something lovely to eat or a babysitter for a few hours.
You might feel much more happier with simple changes.
If he doesn't agree then you need to talk, because you sound resentful already. He needs to pull his weight, and you need to feel valued.
