DD (15 months) is finally starting to sleep better through the night, however the past 4 mornings when I have gone into her she is absolutely soaking wet (nappy, vest, PJ's and bed). She has her nappy changed just before bed at about 7pm but by 4am she is soaked. She wears Pampers baby dry and they seem to fit her well, she does have a cup of cows milk before bed (probably 6/7oz). Has anybody had this issue and any ideas of what I can try as I hate the idea of DD being wet and cold all night
