No no, I don't feel crazy for checking on him every 2 minutes. I feel crazy for following him around constantly to the exclusion of my ability to converse with other adults even for a second. If I supervise him to the extent necessary to make sure that he's safe from this other kid, then I might as well not even be there. He of course, benefits tremendously from playing with the nicer kids there. But I feel like he should be able to do a lap without me following him.
Maybe I'm just being too sensitive to the other parents' criticisms of helicopter parents.
How could you be a helicopter parent when you KNOW this child has hurt other kids in the past?
Would you really CARE if they called you a helicopter parent for ensuring your child is safe?
