I agree ^^^^ listening to your child, allowing her to express her emotions, validating those emotions and offering to soothe them goes a long way. It's difficult when you yourself are a bag of emotions, but in my case it has helped my daughter understand that I feel those things too, and at the tender age of 8, she in turn allows me time to process and respects my need to be alone sometimes.

I lucked out She's pretty amazing
