i never really owned anything smaller than 000, didnt see the point
my girls were 7lb 5oz and 8lb 1.2oz
That is funny as I never bought anything smaller than 000 assuming the exact same thing, we had one 0000 a friend had bought, but I never removed the tags as I thought it very unlikely that we would need a suit so small so after DD1 was born DH, our Family and Friends all went clothes shopping, and DD's first clothes were PP Teddy Bear Clothes, I couldn't have imagined the 000 on her
