trying to figure out when to send my son back to school. His surgery was 3 weeks ago today but it's still not safe for rough play or a lot of physical active. I don't have confidence in his teachers or the lunch staff and to boot he is not himself he gets angry easy flips over everything and doesn't listen..I don't want to keep him home until may 4th which is when he is completely healed but at that point he's missed so much school and there was already talk about holding him back in SK because of the issues he's already has had..ugh what to do 😧😓
