I can't believe all the blokes who get away with being all feeble: "Ooh, I dunno how to change a nappy, I might drop the baby."
I have plenty of friends who do as much as they can, on looking after their own kids side of things. Once my daughter was weaned, I took her out all day, when my wife laid round the house / visited her mates.
I even managed to fill the grab bag wit a towel, nappies, fruit, snacks, drinks, wet wipes, spare clothes, cuddly toy etc. Any bloke who can't even manage looking after his own kids for the day ought to have unpleasant things done to him, until he is capable.
It's fucking risible. And yes, I'd changed a fair few babies, but when mine was newborn, I was worried that I'd hurt her. My wife said, "Don't worry, she won't break."
Somehow, she didn't break, just in case any lazy deadbeats are reading this.
