My tip for today is, if what you're doing is not working then be willing to try something new. Proverbs 19:20 says "Listen to advice and accept instruction, and in the end you will be wise." Proverb 12:15 says, "The way of a fool seems right to him, but a wise man listens to advice."
I read some information yesterday that I wanted to pass on in case you may need it. It speaks of how to handle temper tantrums while on vacation (or at home). Although this was a secular article (I only say this because I usually only read Christian articles/authors) I thought it was helpful. Hope you find it helpful as well.
