My son is THAT child.
He is the one hurting your child, disrupting the kindergarten class and encouraging your child to join in with the silly behaviour.
He is the one who will push or punch or pinch your child if they’re having a disagreement. He is the one who reacts impulsively. He is the one who might throw something if he gets upset, and inadvertently hit someone.
I am the mum who is in daily contact with the classroom teacher. I am the mum who thinks every school pickup is the walk of shame. I am the mum who recognises the school number calling on my phone and my stomach drops. I am the mum who sees judgement in your eyes when I introduce myself as “so-and-so’s mum.”
But most of all, I am the mum who is sorry. I am so sorry that my child hurt yours, that my child’s behaviour affects your child. I understand your dislike and that you’re upset, I would feel the same.
