Wnt2beAMom don't worry, you can't offer the breast too much, if they don't want it then they will let you know and they can't be over fed! I don't believe they should get hungry, they should have whatever takes their fancy and whenever they ask.
It's their main meals, drinks, snacks and comfort all in one so if you think about how often you would get one of those things for yourself and the varying levels of how much you would have them in different days it's just the same.
To be honest my strategy has always been to offer a feed for every little cue, all crying etc and if it's not fixed by that then try other things.
Sometimes I'll offer and there will be fussing so I'll wind, nappy change and offer again. Then I'll try rocking if she's tired or playing if she's bored.
