I do find the grape hysteria on mn interesting.
It is one of those things where, to me, the parent retains control insetad of teaching the child.
So, I taught my kids not to pop grapes or cherry tomatoes in their mouth whole, but to bite into them. By abotu 2/3 they were able to do that pretty consistentl and there was no problem.
I was probably one of those parents who put out grapes at 4/5 year old parties, at it never occurred to me that people don't teach their kids to bite.
I know grapes are a serious risk, becuase they get stuck, but I cannot be everywhere that my kids are, so I taught them to bite into them instead of popping in your mouth.
Interestingly, when I was a kid seedless grapes were rare and expensive, so you ALWAYS bit into grapes, then picked out the seeds, and then ate the pther half!
One of those times when foof inovation is a backwards step.
