Sounds like he's tricking you like my DD is DD is still asking for it at bedtime and lunchtime nap's.....and I let her.

It's funny you say that about your DS giving you kiss's because DD has been doing that ALOT lately too!! She's always been affectionate and loved kisses but never this much!! So maybe that's why.....when I read what you posted I was like "oh me too!" it's so sweet hey.
And i'm getting alot of cuddles too, lot more than usual!
