Is it just my son?! 10pts!?

Garrett just turned 20 months today which is bittersweet, I love watching him grow and learning new things but sad to see him not be my lil baby anymore :( anyhow lately he has been licking everything he sees, like the other day I asked him if he wanted a bite and he spit out his pacifier and licked his toy truck? Today he licked the popcorn bag and when he is eating on his own plate he licks the plate and tries licking everything up...what got me to ask this question I just bought him new bath toys and he was holding them and he picks it up and starting licking it!? I laugh and tell him not to lick things cause I would hate for him to lick something he shouldnt!
