Help! My 21 month old baby boy is hitting other kids. At play dates and daycare. He’s shoving them out of the way too to play with toys and throwing toys at them. Is this just a phase? He also says sorry afterwards. I’m now wondering does he know what he doing or is he not truly understanding sorry. We have redirected and correct and continue to do so. Have tried time outs. It seems it go in one ear and out the other. I do realise he’s only 1 (but nearly 2). Please help. I’m distressed
