Twenty kisses

Every time Fintan is about to go to sleep, at night or at nap-time, the last thing I do before I lay him in his bed is give him twenty kisses. I kiss him all over his cheeks and forehead, and number 20 is square on the lips. I count each kiss out loud as I go. Sometimes I count fast, other times more slowly, but I do it every time. I've never tried to teach Fintan to count to twenty in any other way, but he does it easily now. Maybe I should start giving him 30 kisses?
