DS1 is 4 years old, and has just got his 5m swimming badge (very proud ) which they do at the shallow end of the pool where he can touch the bottom. But he's now moved up to a class where they take them out of their depth, and he's terrified and refusing to jump in or swim, despite the teacher being right there with him.
Anybody had experience of similar? He's perfectly capable of swimming but panics out of his depth.
