If you have little boys and want them to help around the house, try making them feel REALLY BIG to be able to do this job! LOL
If I ask my son to do a job he usually won't want to do it. But if I say something like" Do you think you are big enough to do a big, helpful job for Mommy?" He will usually say yes, and I will say "Are you sure you are big enough to do it?, Can you do it all by yourself?" "Wow, I didn't know you were big enough to do that big of a job!" LOL
But it works!
Flattery for men at any age works! Besides it make them feel good and important and helpful!
Try it! Good Luck!
