Hi all, without trying to drip feed, my DS is 4.5 and was potty trained at age 3, very rare accidents until the day he had his mmr booster at 3.5 and since then (every day for past year) he has at least 1 accident a day, not normally a full wee but enough to need a change in trousers. He starts school next week and we are still awaiting a referral to a specialist. I am thinking of getting him some potty training pants like these Bots Washable Potty Training Pants 4pk Extra Large with PUL Lining - Boy (approx 2-3yr) www.amazon.co.uk/dp/B001JD4QH0/ref=cm_sw_r_awd_5KI2vbRSGN5BH but they only seem to go to age 3. Does anyone know if they're likely to fit my 4.5yo before I shell out for them (or have any other ideas?!). I'm hoping they look "normal" enough to not be noticed by the other kids. Up to now we've been using normal underpants but it can't continue when he's at school.
