With a ton of respect for your superhuman ability as a single mom, OP and her husband are in a totally different situation. Using SHOULD seems super judgemental towards the husband, when it sounds like he's contributing. Just because it's not what you and OP wish, it doesn't mean he isn't doing a lot. What should have happened and what should happen now is for the couple to sit and discuss what they want from each other in the child rearing area. Perhaps, when he wakes up, OP's husband take them ice skating and then out for hot chocolate in a totally cool family outing. IDK and neither does anyone else on Reddit.

Peace.
