My three year old had always been quite tantrummy but he's having some epic ones which I'm struggling to manage, particularly while dealing with a baby at the same time. I know all the strategies to avoid them in the first place (making sure not hungry/tired, giving him lots to of warning about what we're doing etc), and I also know that he's probably having them partly due to stress of new sibling (although he treats his younger brother very well). What I'm struggling with is how to deal with it once the tantrum has started. He will not be reasoned with or distracted. He gets incredibly upset, crying and shouting, and it's usually about something impossible to solve (today he realised as we arrived at playgroup that it wasn't the one he thought he was going to - cue horrendous meltdown, refusing to either go in or go home, and I couldn't pick him up as had buggy with baby). I end up shouting which I hate as he's upset and not doing it on purpose of course. Any tips? Thanks.
