It does get easier, you can't expect yourself to instantly know how to take care of the house and two kids at the same time. I'm just now starting to get minor cleaning done during the day but most days I'm lucky if I can even get the dishes unloaded lol. It's okay not to have the house perfectly clean :) this is a hard adjustment but you can do it just give yourself some time :)

Don't worry momma chores are not important now. Focus on your babies you'll get into your new rhythm soon!
