I'm subbing
Mater 4/5 has always been this way. At the last min he screams and runs to the loo often not making it.
At night time I take to the loo before I go to bed and if he's had a lot to drink that night I will take him again when I feed DD during the night.

I'm really interested in the incontinence nurse idea
Hope you can start to improve her TT soon
