Re: How to tell when baby is hungry?
Increased crankiness, unwillingness to accept alternate ways of soothing, acting tired, crying- those can be good cues that your baby néeds to eat. Hopefully you never get to crying, which is a late indicator of hunger.
Do not worry for one more moment about "snacking". Not even one. Frequent small meals (a.k.a. snacks) are the normal eating pattern of babies, toddlers, and small children. They are especially normal for breastfed babies because breastmilk digests fast and infant tummies are tiny, and because frequent eating helps maintain nice even blood sugar levels. Only older children and adults can be expected to have an eating pattern where they take in infrequent, large meals, and it's probably not ideal for them, either. There's research which shows that people who don't snack take in more calories overall and are more likely to overeat than those who eat more frequent and smaller meals.
The other thing you don't need to worry about is the hindmilk. Trust your baby! He will be able to get the hindmilk he needs as long as you allow him to set his own time limits at the breast. There's no reason to think that a "meal" pattern of eating encourages more hindmilk consumption or more thorough emptying of the breast. You actually cannot offer the breast too much!
