Feeling like the worst mum in the world. I was getting dressed this morning and my 2.5 year old suddenly attacked my 5 month old. He had bloody scratches down the left side of his face. My toddler is normally so sweet with him - lots of cuddles and kisses. He’s never shown any jealous towards him before. I had my back turned for a couple of minutes. My toddler admitted doing it but can’t say why or seem understand it’s wrong. I just don’t know what to do.
