I watched my grandson's from birth to 5 years old. They love to cook ( or least climb on bar to mix or something). My youngest has gone thru more bottles of Windex and Pledge then I can imagine. I did play boy things too, they were throwing balls since they were able to stand. We play in dirt, fight, and even played with dolls. They moved 2 weeks ago and I really miss that time. My husband who is city raised and his father didn't do anything ( i really mean anything) around house, had to learn how to wash his clothes. After he mastered ( in his mind) that, the next rule was I cook , you clean. No it's not perfect, but everyone, be it male or female should learn how to survive in life. Go for it Grandmaw teach him everything, cause football alone will not get you through life.
