Hi, it is hard to find for that little baby! my baby was 2 lbs when she was 3months old too and remember I could not find any at all around so I had color for awhile.
She finally 3.1 by 5months old and found store sells B.B and she is now 6 months old and 3.5's lbs and size 2 is the perfect fit for mine.
