My 3 youngest (Sabrina, Sassy & Josh) have been licking everything since they were tiny. I got them as 2 week old bottle babies, so not sure if it's a nursing thing, or if it's genetics. These 3 young ones will lick EVERYTHING, your skin, your hair, your clothes, the furniture, my shower curtain, sometimes the floor, basically anything. It's rather cute sometimes, but other times it gets a bit annoying. lol I wouldn't trade it for anything though because it's just so 'them'.

Pooky & Bear were bottle babies but got them at 4 weeks old and they don't lick everything.
