It helps my son, obviously every child is different but there really is no harm in giving it a go. I found either leaving it on constantly helps or putting it on about 1 and half hours before bed time. So lucky the people on here know exactly what the other parent is going through, and I know what you mean I always question what have I done wrong, why does my son hate me, am I not meeting his needs. But look at it from your child’s point of view and I bet they wouldn’t change you for the world just like we wouldn’t change them x
