investigating the tongue and breastfeeding

Lifting the Tongue: Arguably the most important skill is lifting the tongue. Not only does a baby need to learn how to lift the tongue, but the tongue needs to have the mobility necessary to do this.  If there is a restriction of some sort, it may prevent your baby from lifting the tongue adequately no matter how hard they try.  This restriction could be from a variation of anatomy (an "oral tie" would fall into this category).  But it also could be a functional inability due to strength, tightness of the neck or jaw, or something else that is keeping that tongue from moving up as needed.
