We have the exact same situation right now. My son is 26 months old, and I am 7 months pregnant, and only I can put him to bed, soothe him, etc. As you described, he loves being with Daddy, but if I am in the house, he needs me there too. My husband says, however, that he is perfectly fine and happy when I am not there. Like you, I am getting really frustrated and tired from all this. So we're going to try having my husband do all the night time routine up until tuck-in, when I'll come back and cuddle with my son. I may try to head out to the gym for quick 30 minute workout, or run to the grocery store or Starbucks for the first few nights, so the boys are home alone together. Of course, none of this plan has been tested yet. Good luck!
