Bottle feeding is significantly different than breastfeeding. One of the main differences has to do with how the bottle nipple is shaped. For the most part, bottle nipples are longer causing the baby to suck from the back of their mouth rather than the front when they are breastfeeding. Another major difference is that the bottle is not attached to anything meaning that the full weight of it is resting on the baby, usually directly in front of their face rather than off to one side. Both the weight and the unilateral feeding direction can drastically impact how the baby eats and can even impact vision and jaw development. 

In this episode Michelle discusses the difficulties that are sure to arise from the new CDC guidelines regarding milestones. There is hope in all of the confusion and uncertainty that will come from these changes. It is important to remember that guidelines are not meant to be exacting rules. Each child is meant to move from birth and can be helped to do so regardless of the new standard set before them.

Development is not task based but rather whole body based. So many of our measurements in milestones for babies is based on what they can do (hold a bottle, etc.) rather than how they move through their whole body. Much of a baby's body presents as a fluid in its motion and interruptions to this fluid motion can be detrimental to how your baby develops and moves.

There are and should be whole body responses to stimuli.
