I'm wondering whether to just stop using nappies, put him in pants, and see what happens. If no progress over the weekend, go back to nappies. If some progress, over to the nursery to continue the good work (tee hee). What do you think? Am I mad? He's 2y4m, doesn't have all GF's signs (only just getting interested in his clothes and nappies often wet); but he's very big and the nappies are getting a bit small! Don't want to go to pullups because they are so much more expensive.
I shall sit back and await your wisdom...
