Babies Can't Read a Clock

Despite the conventional "knowledge" that babies eat every three hours, that's actually just the *suggestion* of a few baby books, and ones that have been largely discredited in terms of what is most healthy for children's growth and nutrition. 

On cue feeding, that is, feeding babies whenever they are hungry, is the healthiest way to feed a young baby. For a breastfed baby it is especially important because on cue feeding ensures a well-established and well-maintained milk supply. 

So, in short, when babies are hungry, they should be fed.  If that's at home, great. If it's in the aisle at the grocery store -- well, babies couldn't care less what time it is or where you are. The great thing about breasts is that they are always ready to go -- the milk is always ready and always the right temperature. Go, mother nature!

This is exactly why laws are in place to protect babies right to breastfeed where ever and when ever they need to do so. Healthy babies and healthy milk supply depend on it. Those who suggest mothers "schedule" their outings so they don't have to breastfeed are either just ignorant of how babies and breastfeeding works, or don't care. Neither reason is compelling to me.
