Looks like I'm on the other end of the spectrum
I only cut up food until 18 months and then it's a free for all. Grapes? Raw carrots? At 18 months I think children NEED to learn how to chew food up so its digestible and safe to swallow.
I've never had a child choke on anything while in my care and while that won't always be true, all my children sit correctly while eating which I think reduces the risk of choking
