He was completely dry at night, but for the last couple of months has been weeing in his bed - I think it happens first thing in the morning about two or three times a week.
We never make a fuss of it, just change him and take the sheets off and if it is really early he climbs into bed with us.
But I was wondering whether it was worth going back to pull ups - it would certainly be easier in terms of washing sheets every day!
