Ds is 2 years and 7 months. Today we told him he was a big boy and he wears underpants now in the daytime.
First pair - accident
Second pair stayed dry, and a wee was found in the potty. No idea when he did it, he must have been quick.
Took him to supermarket - no accidents
Not quite quick enough when we got home "mummy I have a wee and I need to sit on the blue hole"
An hour later a wee on the floor
1/2 hour later "mummy I've weed in the tent" Very impressive use of past tense, very impressive amount of wee in his playtent.
Then dry until his pyjamas and night nappy went on. So 3 wet sets of clothes, and one potty wee that we didn't see.
Sound about right?
