If redirecting attention doesn't work I go outside with him, the fresh air works every time. Or if it's at night I'll go into the bathroom and turn the light on, let him look in the mirror or look at him through the shower screen..
He does it very often in the space of like 2mins, how can I constantly take him out or bathroom if I have other things that need doing
My son does the same... I just try to comfort him by giving him a cuddle or picking him up usually he calms down very quickly. I sometimes get annoyed and overwhelmed by it but I try to think of it as a phase and calmly react as if I get frustrated he will sense it and it'd be even worse. Hang in there 😊
