OMG it is sooo awesome! My DS gets lots of cuddles from me and DH and loves them. He voluntarily gives us lots of hugs and kisses. Of course now that he is walking sometimes is too 'busy' LOL but he is really affectionate little guy. I think humans are naturally very affectionate and allowing them to be that goes a long way in encouraging hugging etc. We also never force him to hug or kiss anyone so he only does it when he wants to. And he does it a lot!
