My son is the same way. I can't keep him inside. He loves to be outside. Just let them explore everything. If I know if it's not going to hurt them, let them experience it. Even if it's going to hurt a little......At least you would hope they wouldn't do it again. My son finds other ways to do things so he doesn't get hurt. Takes him a few tries but he never gives up on anything. Little scary. My daughter is the complete opposite. If it looks like it might hurt, she'll ask for help or not bother. My son likes to move, more like run ever sense he was 10 months old. It's hard to keep up with him. I'm not to worried about the fire pit at night while the fire is going. last year the heat was enough to keep him away from it. He knew. It's the next morning that worried about so I bought one of these Superyard XT - North States Industries - Babies "R" Us for him to play in but he didn't want any part of it so I use it to go around the fire pit in the morning so he and the dog don't fall in. Last year was easy because he was just crawling around now this year will be different. We'll have to see. My daughter is 7 and my son is almost 2. She's been a big help keeping an eye on him. She's the informant. She tells me everything he does when I'm not looking.
