Is it too early to buy things?

Lauren • Mommy of 3Z's.
Yesterday I was in target and they had a really nice sale with baby clothing marked down up to 70%. I couldn't help but to get a few little outfits (they were pretty cheap...$3,$4 each) but I was told it's too soon to shop. With my first I didn't start until 6 months or so and I honestly don't remember when I started with the second. Has anyone else started shopping?
