I'm not an expert, but I had several college courses in psychology and my daughter has mental health issues, so I've done a lot of reading in this area. If there is ONE thing you can do to help your young children through these very emotionally difficult times, it is to make them feel SAFE AND SECURE. Remind them over and over and over again that you will ALWAYS be there, that you would climb mountains or walk through fire to make sure they are safe with you. Tell them over and over that you are not ever leaving them and that no matter what they do or how they behave that you will always be there to take care of them and you will always love them. Buy them a special teddy bear and tell them it is to remind them of your love and constant presence and that they are always your very top priority and NOTHING is more important to you.
Tell them this every single day....morning and night....over and over again. (((Hugs)))
