oh and he can't have a drink once it's 1 1/2hrs before bedtime. - if it's hot and he's thirsty - just a small sip. She said to aim for 8 drinks a day, last one no later than 6.30 (now moved to 7.30 as I've moved his bedtime by 1hr).
Was told not to bother lifting, and it doesn't help them learn to wake up when they actually need to wee.
Oh and another tip - which really does seem to work is
When they get ready for bed, do a wee, brush teeth, then do another wee straigh afterwards - for some reason they really do (I get DS2 4 - who's been dry for 1yr of his own accord) to do it too - they managed to empty more of their bladder after brushing their teeth!
