They let my 14 month old put 2 whole grapes in her mouth

What would you do if you found out someone who is responsible for babysitting your child let them out 2 whole grapes in her mouth.

Well this happened to me.

My child is 14 months old and has only 4 teeth!!! Most children her age have way more teeth. And my in laws knows this. They also raised a kid in the family so being around babies isn’t new to them.

What would you do. What would you say? Also these people are my in-laws. I was in the other room when it happened. I ONLY knew it happened when I saw my baby spit out the 2 grapes from her mouth.
