Tiny baby sizes= way off for meMy boys were BOTH 9Lb 1oz at birth.
They both gained 2 pounds per WEEK for the first few months.
They wore 0-3 months from birth.
They wore 6-9 months at 3 months
They wore 12 months at 9 months.
After this age they SLOWED WAY DOWN.
After they turned a year, they were always exactly in the year size.
1 year old =wore 12 month
2 year old wore = 18 months-2t
mine grew at first, and then they stopped.
