Yeah, my daughter will be six in Dec. My son just turned 4 less than 2 weeks ago. He loves to help me clean, cook, decorate cakes etc. My daughter, just about have to threaten bodily harm to get her to clean anything! She also doesn't enjoy cooking or baking with me nearly as much as my son. I have to pull the old "Tom Sawyer" on my daughter to get her to clean or help me most times.
He also wants to do everything she does so he wants "homework" like she has. She's not as interested in doing hers as he is in his.
Guess there's something to "having" to do it and just wanting to do it for fun, cuz she used to love to do "homework".
