Not trading in my cleaner for ANY floor cleaner, I love her more than DH 
Ipsos May I (as a person who has medication for anxiety) respectfully offer an alternative opinion? My teen DC have never once caught me being anxious or seeing the risk about anything. I have never told them not to climb the highest tree or jump over the widest ditch or go hell for leather down the biggest zip wire, I never stood at the bottom to catch their fall. When they were little, they were dropped off at nursery and I was gone, I didn't stand at the top of the road taking pictures when they started high school. They have had to sort out friendship issues themselves to a large extent, although I wouldn't allow bullying I guess. They have been sent into their little worlds believing they can do f**king anything, and they honestly think they can, especially DD, to be honest. Some of the stuff she does on that pony leaves me quaking, but realistically, she has a back protector on and a hat, she's safe (sort of!)
I drive a dirty great horse box all over the country, which I hate, but DD has no idea I hate it, my anxieties will not impede her goals. Actually, doing it, has made me realise, it's not so bad after all anyway 
I think we should spot risk, for sure, but hide our adult emotions to our fears to some extent. I honestly don't mean allow them to do something dangerous, but they have to feel the fear and have the confidence to do it anyway.
Having been a parent for 16 years now, I figure the less you stress and worry, the more confident they feel 
Just IMHO
