Baby obsessed with other peoples’ hands

K

Okay, guys.. my 9 month old boy is OBSESSED with playing with peoples’ hands. Holds onto our fingers, “talks” to them, smiles.. etc

Please tell me my boy is normal! It seems so weird to me.. and I can’t find anyone or anything that relates to this online (I just keep seeing autism articles.. WUT?)

Anyone see this with their l.o. before?
