DD1 is 2.5, turning 3 in June, and still holds all writing utensils in the fist grip. I thought that was still pretty normal for her age, but at playgroup today, I noticed a lot of the kids around her age were holding their crayons with the correct (or pretty close to correct) pencil grip. It's not something we've ever really worked on, although I am starting to encourage the correct grip now, but just wondering when other people's LOs started using the correct grip!
ETA: fixed the poll to allow for multiple votes!
