DF isn't a SAHD but he does have our kids more than I do (when I am not on maternity leave). He works an even time roster that essentially works out that he works 5 days on then has 5 days off, while I work mon-fri.
He does well. He takes DS1 to the park etc and he does a lot of the house work. I still do at least half of the house work and we split the duties once I am home from work.
