Thoughts on instant gratification

I have been thinking for a long time about the role of breastfeeding in infant development and growing up. I have come to an interesting insight. When formula feeding, the moment the bottle is in the mouth there is food coming out - instant gratification. This happens from the first feed forward. There is no wait and no no learning. With breastfeeding, the infant goes to breast and has to work to suckle, there is the comfort of being close to Mother's heart and touching Mother's skin but there is not an instant food reward. In fact, there is a lot of suckling that goes into getting the first little bits of colostrum out and there is a lot more suckling that goes into bringing in the milk. In fact, it is work to get the breastmilk out of the breast. Now, we know that breastfeeding helps decrease infection. Breastfeeding also helps with facial development and eye development. At this point, I am thinking that breastfeeding also helps with learning that instant gratification is not the way of the world. Breastfeeding lays the foundation that one has to expend some effort in order to receive pleasant things (i.e. food). So not only does the breastfed infant learn to feel safe at the breast, the infant also learns the very basic idea that one has to work to gain things one wants - there is no instant gratification.
