Toddler ate my newborns umbilical cord

So our curious toddler ate our newborn's dried umbilical cord that had just fallen off.....only reason we know is because he didn't get through all of it, apparently we don't feed him enough!!!! 😭...anyone else have this happen with their kiddo?

Edit: my wife called poison control and they said this was a first(LOLL) but it probably would be okay since it's just connective tissue, I guess we'll see....🤢
