My son will be 5 in April and honestly he does have a whining problem and he does cry a lot but I see my little man being just overly sensitive. For example if your playing around and say "did you fart woo wee it stinks" his feeling will get hurt and he will scream and cry. My daughter on the other hand will laugh and joke back with you. She's super tough and a good sport about things.
I just feel bad for both my son and my dh because hubby is a true manly man and I know he wants the same for his son.
Thanks for letting me vent.
