Single parent to 3 children. Have always enjoyed parenting the oldest 2, now 8 and 7. Youngest (5) I am finding much more difficult. She can be so fun and affectionate but she’s very volatile and will lash out when angry. I’m struggling to know what to do. I’m trying to set boundaries, e.g. after she kicked off about her shoes we didn’t go to the park, but I’m not sure I’m doing it right and it doesn’t seem to impact future behaviour. AIBU to ask for advice? Does everything just know how to do this?
