Hi D.,
The dry nights are, in my experience and from talking to other mums, a rare delight for toddlers being so young (and mums). I have two daughters, a 5 1/2 year old (and a 20 month old), and our first still wears pull-ups. Another friend of mine with two girls, said one of hers was in pull-ups at night for well into her 7th year. It does seem like a long road but certainly at 2 1/2 years old I wouldn't worry yourself. From what I've heard, this part of kids development, is different for everyone. I just take the attitude that unless there is a reason for bed- wetting that is not developmental like nightmares, stress at home, stuff going on at school etc etc, kids will do it in her own time. For us, sometimes we have dry nights for a week at a time, sometimes for a couple of days and then we'll have constant wet ones for weeks at a time. What I am seeing over the long term, however, is progress. This one, unfortunately, takes longer than we would all like....just give support and praise when things are dry and don't place any negative attention on the wets. Hope this helps.
I am a mum of two (as above), an Australian who moved here last April with English husband. We live in Battery Park.
