i bought two old style HH prints off the TP in small. i looked on the website, and they are supposed to fit to around 16 lbs - well, these two are fairly snug on my dd, who is only just over 12 lbs. then today, i got an FB from the TP, also size small (supposed to fit to 16 lbs), and it fits great with plenty of room to grow. . .so i guess my question is. . .do HH's always run small? or is there a problem with these ones? or are the old style prints sized different?
