I personally don't think your baby will be over 6 pounds...The growth chart on here may not be accurate for everyone though...Pixie was probably under 1lb 8oz at 12 weeks old as I didn't get her until she was 14 weeks old and she was 1lb 8oz when she came to me...so doubling that weight would make her around 3lbs as an adult....well....she is just under 3lbs at 14 months old!
