DS has just turned 2 and started at a new nursery where they all drink from open cups. At home he has a beaker or straw type cup, we just hadn't thought to transition him.
But we need to teach him soonish as he just holds it up and laps like a kitten, hardly actually getting anything out! He puts his tongue above of the rim. How can we teach him to put his tongue underneath so he isn't going a whole day with minimal fluid intake?
Thanks in advance
