Thank goodness my son who will be 4 in a couple of months (umm they grow up so fast), only like to wear my shoes, and its o-ka-y, i think if he started that i would flip out, when he was younger (and didnt really understand) he wanted for me to put makeup on him and i explained that it was for mommies and not for Coltons, he cried but was ok, i think since they are around us more than daddy they want to be like us cause that is what they see all the time, so what i did was start buying him stuff like daddy, he has the same undies, boots, belt, ect. and he likes it, he is now telling me i wear so and so like my daddy (which is so much better than mommy)!! I hope this helps and he will grow out of it (i hope)!! Good Luck and btw i dont think you over reacted at all, its better to teach now than trying later!!
