Does anyone notice the need to go to the toilet increases with the more food eaten? After weeing loads through night my daughter gets up in the morning and goes as everybody does, then just a couple of times throughout morning, but once lunch has been eaten I see a huge increase, she only ate 15mins ago and has already been twice and its the nursery commenting how often she needs the toilet and she goes to afternoon nursery, and it just seems to get more as day goes on...
