We started potty training and had 4 accidents on 1st day, 2 on day 2 and only 1 on day. I thought it was going really well until she got diarrhoea on day 4. I out her back in nappies until she was better and then tried again. It was a complete disaster. I think she only managed to get 2 in the toilet. What do I do now- persevere, or put her back in nappies for a while?
