how can i get him to help?!

[*angel*eyes*]

after my son was born, while we were still in the hospital, my fiancee was amazing. he took such great care of kale and changed his diaper 99% of the time (i had a hard time getting in and out of bed and sitting up due to my episiotomy).
almost as soon as we walked into our apartment, things took a 180 and now getting my fiancee to do the smallest things like changing a diaper or burping him is like yanking teeth.
i am nursing, so he can't exactly feed the baby, but that doesn't mean he can't do almost anything else.
he works full time and goes to school full time. i worked full time too, but still haven't gone back yet because we're low income and waiting for daycare assistance to come through. i know he is stressed out, but im home with kale all day, and i get up with him EVERY time he wakes up at night.
i feel like im raising him alone and its breaking my heart.
he is a great provider and works hard so we can stay in our apartment and pay our bills, but i get the feeling that either he doesn't want to help take care of kale, or maybe doesn't know how.
any suggestions?

Studying fulltime and working fulltime? He's probably run down. It's not an easy thing to do. But have you tried talking to him about it?
