i think my son is on drugs

i’ll wake up in the middle of the night and hear his toys singing. i’ll peak my head in and he’s in his crib babbling and playing. i went to pee around 3am and i heard him singing e i e i o.he’s up at odd hours and i’m worried. do you think it’s meth? do i need to worry about the kids he’s with at daycare? via /r/Parenting http://bit.ly/2rT2kgM
