The pink or blue question is a moot one these days, isn't it? After all, it's so easy to tell the gender of a baby before the happy day, so there's no need to guess. Well, that's not strictly true. Even with the advances in technology, ultrasound pictures aren't always one hundred percent certain, and many parents prefer to be surprised. If you're shopping for a new baby without knowing the gender, you still might have to decide whether to buy pink or blue. You could always flip a coin - heads.
