DD (2.5) was due her nap so I took her for a wee before putting her down but she was sitting there a while and just wanted to play with the toilet paper by tearing it apart. I tried to keep my calm and ask her if she wanted a wee and encouraging her to go,but she just sat there so I tried to get her down but she didn't want to and got upset when I tried to. Anyway, it feels like from nowhere I just lost it and shouted at her to please have a wee and she just burst into tears the poor thing. I feel absolutely awful now because I felt like I had no control over myself for a minute although I could feel it build up when it was happening. When she started crying I did too and then it woke DS (6WKS) so I got more stressed. Is this normal sometimes? Am I a crap parent for losing it? I feel so guilty now and just want to cry. I just feel like I'm doing such a bad job of parenting sometimes.
