"The Archdiocese of Cincinnati has issued a detailed list of inappropriate behaviors for priests, saying they should not kiss, tickle or wrestle children." - Source
But who would do that anyway? Unless you are Byzantine rite or a traditionalist (they kiss rings and consecrated hands) - or a relative, who would kiss a priest? And what priest in this day and age would ever dare touch a kid? Especially by tickling - that is like torture and wrestling is just gay. But I guess the rules have to be stated in an age without boundaries.
The list includes what is good touch however: "It says priests may still shake children's hands, pat them on the back and give high-fives." I wouldn't even do that.
No more "koochi-koos" for baby either! (This is what happens when lawyers write church policy.)
