My dd was toilet trained in the day at 22 mths and was dry at night for the first couple of wks then started wetting every night so went back into nappies. She's now 4 and nappies are still sopping wet in the morning. She wants to be dry and so on Fri and Sat just gone she wore pants. She went to the toilet before bed and I took her for a dream wee 😃 before I went to bed, had one wet sheet the first night and 2 last night (thank god for brolly sheets) but she was over it by then and asked to go back into nappies. I think she is in such a deep sleep she literally has no idea she is wet or needs to go. We'll wait and try again in a while I think.
