When I sat to feed DS2 I always made sure DS1 was changed, had water and a snack. I also had some toys in a special bag that he got to play with while I fed DS2.
I second that! I always made a lunchbox up when I had time at night for the next day. That way snacks were always quick to grab when needed....

Actually I still do it today for my 'baby' who's 5!
