rewash it with a couple color catchers- a couple washes may remove what ran...it doesn't really seem to matter what manufacturer the fabrics come from- reds tend to run- especially if warm water was used instead of cold. the grandson probably doesn't mind a bit- i bet he still loves it all the same- as long as the 2 of you are not all negative about it in front of him it's not going to matter one bit- he will continue to love it until it's a rag- and maybe longer than that.
