Night Training a heavy sleeper?

[Phteven]

You can visit a physio who specialises in urinary incontinence although 4 is probably too young to bother because he might have grown out of it by the time he is old enough to see one.

It might sound a bit odd but our physio asked about constipation - apparently a lot of children with night wetting problems have constipation. Often using something like benefibre and increasing liquids can have very quick results.
