listening to your baby cry for an hour while dad burps him and changes nappy, and you are cooking tea, only to come in and find baby laying down alone while dad plays xbox.

(after we had tea, I picked him up and sang to him for 30 seconds, and he was out like a light)

So I guess my point was having to let dad make his own mistakes when you kniw you can do it better/quicker/easier/stop the crying.
