I'm beginning to wonder if this is good for him. I know he needs to learn things on his own. But we don't want to risk injuries. He is 6 yr old and hasn't had any broken bones or stitches. I'm sure we have saved him from many falls and busted heads by stopping the action before it happens. How to I let go of my fear of him getting hurt and let him be more adventurous? And if he does get hurt I have to deal with dh getting pissed at me for letting him get hurt. Now our biggest concern is him doing something without thinking about the consequences and accidentally hurting his baby sister.
