My nearly four year old is constantly having meltdowns. He screams and cries and shouts over any minor inconvenience. He obviously doesn’t know what he wants as he yells at us to go away and stop touching him etc but then cries and begs us to come back/cuddle him. It breaks my heart to see him so unhappy. He also screams and hisses like a wild animal if we tell him no. We do not back down, we try to always acknowledge his feelings while staying firm with boundaries but it doesn’t seem to help. He picks at his fingernails constantly (anxious habit that I had as a teenager that I have mostly under control now) to the point his fingers get infected and he has had to have antibiotics. Obviously i can get him fidget toys etc but I would love some advice on how to coregulage when he is like this. I am sleep deprived (have a four month old baby so jealousy/feeling displaced is obviously a factor) and absolutely loathe being shouted and screamed at, sometimes even hit, multiple times a day. He is at nursery 4 days a week and holds it together there but melts down almost as soon as he sees me. It’s making me extremely miserable. I spend uninterrupted time with him playing, reading each day and praise him often for positive behaviour but I struggle to keep my cool when he has been whining and crying for what seems like hours. I end up shouting which makes me feel sick with guilt as I know I’m making things worse. Anyone had a kid like this who grew out of it?!?
