My dd has been potty trained since she was 2. She did really well at first and became clean and dry really quickly. A few months after her brother (11 months) was born she started wetting herself and doing poos in her knickers. She comes home from pre-school at least twice a week in different clothes. Sometimes they have to change her twice in one half day session. At the weekends she will often go through up to 3 pairs of knickers. Anyone else experience the same thing with their dcs? Please tell me she will grow out of it soon?
