Dd has never liked being kissed on the lips, so of course we don't do it. She's not a big kisser at all, so we let her take the lead. If she wants to kiss us, she'll initiate it. She's more of a cuddly snuggler. Ds will run at you and plant one on your lips when you have no idea it's coming, so we let him. I love it! He's got the sweetest little kisses.
