My husband and I both kiss our two youngest kids on the lips daily. They are 4 and soon-to-be 6. Our daughter is 10, and once in a while she’ll still give me a kiss on the lips, or her daddy. She’s just starting to get to that age where it would be strange, but I never actually thought about it or made a conscious decision to stop giving her a kiss on the lips.
My boys are my boys. They are both at that age where they say, frequently, that they want to marry me when they grow up. The 4 year old will go so far as to describe the various ways in which he can get Daddy out of the picture so Mommy is available. It’s hilarious…but I just remind him that I will always be married to Daddy. Anyway, back to the kissing. My boys kiss me on the lips a lot, but they also kiss me on the cheeks, the forehead, the hands, the tip of my nose, or my chin. We are all very affectionate, and now that this question has made me think about it, I’m kind of sad because it won’t be long before they are too cool for anything other than a quick peck on the cheek. :(
For those that think kissing your kid on the lips is wierd, I will say that it’s nothing like a romantic kiss. Even my 4 year old’s kisses, which tend to linger, are not at all like the kisses I get from my husband. Besides no tongue being involved, there’s no…um…lip play, I guess you’d call it. Just a pucker up, nothing remotely sexy about it. Just a lot of adorableness (except when the kid has a runny nose, and then it’s completely gross).
Edited to say—I think the kids prefer to give my husband a quick peck on the lips because otherwise “it tickles” because of his stubble.
