I'm laughing at all these and it's given me the confidence to post a bad daddy story: I have so many bad mommy moments I have to think more on it.
DD was about 5 months old and had just started eating a little baby cereal. After a couple days she wasn't pooping so we got a little nervous. I looked up a recommendation to give her a little bit of diluted prune juice to help, and I'd mentioned casually to DH that we might need some prune juice. My DH took it upon himself to give her the juice without asking me. So 4oz of undiluted prune juice later we had a dehydrated and very messy, smelly baby

It lasted several days !
