My older child is very involved in football and my younger daughter since birth has always been dragged along. I let her play on the playground (monkey bars included) but will admit I probably don’t look over to check on her as often as my mommy guilt thinks I should.You both are very lucky to have other good, responsible people around to help him. :)If it helps, I’m sure your son does NOT blame you and 10 years from now he won’t even remember.
