What to do when babies are not eating?

Richie wakes up in the morning and makes a fuss to have milk. It almost takes 1-2 hours by the time he finishes just 100 ml of milk. We could not go anywhere in the mornings as we used to get delayed on account of this. Recently I got a nice idea. As soon as he gets up, I dress him up, take all his food stuff and go to the park. He loves nature and feels hungry after a good round in the park. And the very good thing is, he gulps down whatever comes in his mouth. ;)
It works wonders to take babies outside. They feel good in the fresh air and come home refreshed. It is like killing 2 birds in one stone.
