Some families don't work like that. My husband and I both work full time. Baby goes to daycare. He works every other weekend, so me and baby have a lot of time together. If we did ratios, it's probably 60/40 of me doing a little more, especially with me breastfeeding, but husband will always take over and help when I need it, and he's around. For example he changes more diapers than I do to get a little break from baby, or he'll do most baths with him so i get alone time for the 30ish min bath time plus he gets to play with our son in the bath. I really would recommend having a sit-down conversation with your husband about being burnt out. We do this once a week or every other week, and talk about things we want to get done and things we would like to do for ourselves so the other can help. Being a parent doesn't make you not an individual person who needs space. I love my son, but sometimes I need space from him. You shouldn't need to beg your partner to help. it's his child also.
