Can anyone please help me my 4.5 year old wont poo on the toilet or the potty. She hasn't been constipated or had a bad experience she just says she doesn't want to. She will wee in the toilet no problem. I've tried reward charts, prizes, promises of days out absolutely everything. Tried toilet paper in first, a nappy opened up in the toilet, singing nursery rhymes, watching videos. I refused to give her a nappy but she knows they're in the house as she has a baby sister and her nappies fit her and she didn't go for 4 days and then all day today she's been rolling around crying asking for a nappy. She eventually Sat on the toilet to try but cried hysterically for 20 minutes until i couldn't take it anymore. Because she was crying her little sister was crying too! I don't let her see me get upset about it but its really worrying me how she's acting about it and no body seems to be able to suggest any thing I haven't already tried. Any one have any experience with this?
