My little boy is 2, he turns 3 in February and recently he has started hitting out, he lashes out at his big sister and most recently started hitting me in the face when dropping him off at pre school. I don't know where it has come from, it has come out of nowhere, I recently had his teacher pulling me aside and asking how he is behaving at home. We never had this with our first child so this is all new. Is this a phrase? I have started the time out routine but it's not really working. Anybody else going through this or has been through it and what can help? He hasn't had much of a social life as being born 2 weeks just before lock down but I can't see that being the issue here?
