it has been an adventure watching my 5 year old daughter-who normally likes to play with boys & considers herself a tomboy- & my friends 6 year boy interact. what i would like to see is them play together & entertain each other. this is so not the case. i think because they are so much a like that they really don't get along well at all! because he has 2 older brothers, he likes to play a little rough, where she likes to wrestle, but gets hurt easily. they also both need to be in control of the play & then eventually start to fight & tattle on each other. he also gets frustrated very easily when things don't go his way & she gets a little aggressive. we, as parents, decided to get each one of them a small remote control car. this seemed to do the trick...for a while until they found out that they can control the others car with their own remote by a simple switch! maybe as they get older they will grow out of this "stage" & learn to play together better. i guess all we can do is wait & see.
