Am I expecting to much?

Hey mamas, I am mom of a 30 months and a 14 months children

My husband is a teacher and I am staying home and have no salary so he does really a hard work to support family with single income

he do day school, night school

Now he had about 2 weeks holiday to have a good rest

my 14 months recently weaned of breastfeeding and having new teeth at the same time so I really didn’t get enough sleep recently but he is not helpful at all at night time and I’ve had argued with him about that

How much help should I expect?
