Changing diapers

夫が1ヶ月以上ぶりに彼女のオムツを替えた。私が強めに頼んだ後に。

My husband changed her diaper for the first time in over a month. After I asked strongly.

家で働いて見ているからか、育児は私がいる時は何もしなくていいと、彼は思っている。ダメな人は大抵みんなそう思っているのだろう。

He thinks that he doesn't have to do anything when I'm there, perhaps because he's working from home and watching. Most bad people probably think so.

感謝を述べてやる気を出させるか、当たり前として覚えてもらうか、効率的なのどちらだろう。

It may be motivated to express appreciation, or taken as a matter of course to be remembered, or efficient.
