Manipulation?

So a few nights ago I was preparing dinner and Anna-Kate asked me to put her in her high-chair. As she now has a booster chair and I was planning to put Ryan in the highchair (just to sit with the family as he's not eating solids yet)...
JH: "I don't think so".
AK: "peeeeeeese mommy?".
JH: I was busy, not wanting to be bothered..."ask your daddy."
AK: She trotted off and a minute later I hear, "daddy? Hi daddy. I loooooove you. Daddy, I sit highchair please?"
Of course he said yes! It was my own fault. :)
