A member graciously sent me directions on how to make Elmo out of RKT and then cover it in royal icing. This is for a toddler and his birthday party. If the children want to eat Elmo will the RI be edible? I know you can eat it, but will it be too hard (crunchy) to eat?

I suppose it depends on the toddler? does he/she have teeth? lol silly question i know! i fidn with kids, if its sweet, they will eat it i dont think it should cause them a problem, if its too hard for them, they might just leave it, but it wouldnt do them no harm

They can eat it. Should they? This is another question.
Generally, you can soften RI by adding 1 teaspoon of glycerin to cca 1 lb of RI.

For my niece I made cakes for her 2nd and 3rd birthday with cream cheese frosting. And till now (she is 4 1/2) she gets few gingerbread cookies decorated with RI and the rest are plain ones.

I would say the mother decides...

It's edible, but I agree with majka_ze and let the mommies decide. Too much sugar overload

Thanks everyone for your responses. The toddler is my nephew (mother is my sister-in-law). Don't want to do anything to cause an upset.

I'm with everyone else I would leave that to the mother to decide. I can say that when my son was 2-3 he would sneak and "steal" my RI flowers all the time. I would always be sure that I had made more flowers to work with, thought I was losing it- then I caught him with his step stool that he used to brush his teeth, very quietly helping himself to RI daisies that were drying on my bakers rack! Had to find a higher up drying spot. Precious memories, LOL!
