Is it ever OK to kiss children on the lips?

I'm WAAAAAY behind on all my TV stuff, due to tons and tons of work everywhere, mainly keeping up with Forty Forty Baby blogs and Instas and TV and articles!
Now pregnant with my 4th baby, parenting has come full circle for me, and I'm loving it!

But I need to catch up on all my website stuff now, ahead of lots of exciting book things, podcasts coming etc etc

SO...
This was me on This Morning recently taking about KISSING.
 
And how yes...it is absolutely OK to kiss out own flippin' children on the lips - if THEY are OK with it too!

If a child hates it, obviously don't do it. And most kids don't want it after the age of 5 or so, so just sense what's OK, and stop when it's clearly uncomfortable or not wanted. 

Anyone who thinks there is anything sexual or creepy about it when our children are babies and toddlers really needs to ask themselves some serious questions!

And as for lip-smackers from Great Aunt Gertrude...? 
Yeah, I'd say not. REALLY not. 

What do YOU think? Do you kiss your kids on the mouth?
