The truly hard part is putting them to sleep

I agree, I never found changing diapers that difficult or bad. I was also hardened by years of chronic insomnia so the sleep disruption wasn't a big deal, I took most of the night-time duties to let mom sleep.

The thing I remember being most annoyed about was cleaning all the bottles. That was really obnoxious.

Honestly the hardest part of changing diapers is when they get bigger and insists on wiggling everywhere while you are changing them
