I love this gown.  The solid colors are great for matching to hats and blankets.  This size is perfect for baby as soon as he is born.  The upper body is small but stretches and the gown is extra long for long babies. He has been wearing this gown from the day he is born and still wears it and he is three weeks old.  He weighed 8-2 when he was born but I think a smaller baby could wear it also.
