Re: Daughter in daddy's lap
I would never sit on my father's lap. I am almost 32, but after I turned about...I don't know, 10 or 11 tops, I wouldn't have sat on his lap. It would feel weird to me. Just as, after my sons turn a certain age, it will be weird for them to sit in my lap.
Children are only children for so long. While they are children, they can do things like sitting on our laps, because they are littler than we are, and we are their parents, comforting and loving them, perhaps protecting them. Once they are adults, even though we still look upon them as our children, the fact is they are adults and therefore technically our equals. You expect the same maturity of her that you expect of any other adult, and part of that maturity is not sitting on her father's lap anymore. Part of it is also probably....not jealousy per se, but a sense of since she is a grown woman, it strikes that chord in you of seeing another woman on your husband's lap, which would naturally bother you.
I would just tell her honestly that at her age, she should stop sitting on her father's lap. Hugging him, a peck on the cheek, whatever, is fine, but the lapsitting isn't cool anymore. IF, and this is a big IF, she or your husband act like you're out of line or continue doing it, then you might consider that there's something more to it.
