Lucas started training in the July, he was 3 in the October, so don't take it to heart hun. Boys have a tendency to be slower on average when it comes to potty training.
Like Lewis, the potty was always a no go, which did make it harder than with the girls as you can't leave a toilet lying around like you can a potty!
When you do decide enough is enough and decide to bite the bullet (boys are stubborn creatures) I'd prepare yourself to be stuck indoors for a few days and have a load of pants and trousers ready for all the accidents. A lot of people swear by letting them run around either butt naked or just with pants on, but I have always got them properly dressed (it helps soak up accidents

). Yes it's frustrating and yes you wanna scream "How hard is it to tell me you need the toilet?" 10 times a day, but somehow you always manage an "Oops oh dear, never mind" Take him to the toilet around 20 minutes after drinking and keep taking him every 10-15 minutes until he does something. Yes it's monotonous, but eventually he'll hopefully click that if he does something he gets left alone (until the next time he has a drink!)
