I'm risk-averse when it comes to my DSs, probably made worse because of DH and MIL's much much slacker (IMO) attitude to their safety.
DH can't see risk until something has happened, whereas I can see the potential for it beforehand.
So DS1 fell out of the trampoline chin first onto concrete, because DH hadn't considered the possibility, and therefore hadn't closed the zip on the net. AFTER it happened, of course, DH was adamant that the zip should be closed every time as I'd told him beforehand
DS1 could have drowned in the lake aged 2 or 3 because MIL decided that she was quite able to take him out in the water by herself while DH was fishing on the jetty - except that he was baiting his hook and not watching when she slipped and lost her footing, submerging herself and holding Ds1 just above the water - luckily for all concerned, DH didn't take too long baiting his hook, turned round and saw the problem, so flung himself into the lake to rescue them, ruining both his rod and his phone. I'd also told DH that MIL wasn't to take DS1 in the lake by herself because of the risk of her slipping. She has never done it since.
I'll let DS1 walk to school by himself when he's older - he's 7 now - because he has 2 very large main roads and 3 side roads to cross. No way is he doing it now.
DS1 nearly choked on half a grape when he was around 1 - so I cut them into quarters for ages. DS2, however, has always been a chomper, but also a face-stuffer, so I cut his grapes into quarters too. Not now he's nearly 3 though, even though there's still the risk he could choke - he's far more able to chomp them so I think that's less likely.
I prefer them not to run down hill because it causes me anxiety, but they both seem fine with it and do it anyway, unless it's a complete scree slope.
I prefer them to hold my hand when walking on the oyster rocks at MIL's place, but DH and MIL don't bother, so they regularly have chunks out of their hands/ knees from falling when I'm not there. I don't mind them falling over elsewhere, just oyster rocks are bloody sharp and can get infected like coral cuts.
I know I'm a bit too precious over them, but I'd rather that than blame myself for letting them do too much and then have something awful happen. They're not wrapped in cottonwool, though - mostly covered in cuts, bruises, bangs and scrapes from playing outside (and in!) - but generally in one piece.
I may still refuse to countenance either of them ever getting a motorbike though...
