6 yr old boy - only child, not very competitive due to sensitive nature. Gets really upset when he loses anything from board games to 'race you to that tree!' type games. I can see how frustrating it is for him, he bursts into tears, shakes his fists, clenches up, gets red, etc but what can we do? We sometimes let him win but when he's playing with other children they don't and (rightly so) shouldn't have to. Any ideas or suggestions? Could it just be a phase or an age thing? Or are boys naturally competitive/sore losers?
