textbook baby?

Why don't I ever get the textbook baby?
Does anyone ?
The latest baby is giving me a small cause for concern - logic tells me that all must be OK , but I have only seen him feed twice , on both occasions with a bit of prompting from me - but he must be feeding , he runs around like a mad thing and would surely have run out of energy by now , but I would just like to see him feed !
He was up and looking for food really soon after birth , and I have seen him nosing around the milk bar , and he shows no signs of being hungry ...... he must just feed when I'm not looking . I want the textbook one who feeds whenever I look out of the window and gives me peace of mind !!!
