No... I would let them choose once they got to school age... most children know by the time they are one what their favorite color is...
serena is girlie girl through and through... she was a PINK BABY... all she wanted was pink... and still does...
same thing with toys... buy both and see which way the child leans...
plus there are switch gender clothes these days... can't go wrong with t-shirt and jeans...
Serena wears boys jeans because she is so lean in the hips but has long legs...
