Excessive moodiness

When my daughter holds in all her frustration from her day at school, she explodes. If then she hasn't eaten on a regular schedule that day she becomes physically agressive. This is hard to handle. It's hard on her grandmother. I wasn't the same as a child and it baffles grandma quite a lot. Asking my daughter to hang up her coat becomes a struggle on these days which lead to temper tantrums and ultimately my frustration. At these times I try to keep calm. Most of the time I can, however when you are being hit it's hard to be neutral. I tell her how her actions affect me and then we discuss the day. We ask for God's guidance and I pray for patience. This is what helps us at the end of these days.
