I did and although i loved the way they feel and they were so cute they just didnt fit. I got the M/L , way too small, they didnt even come close to fitting ella and she only weighed 18 lbs at the time. i emailed the wahm i got them from and told her, not that i thought it was her fault, but i thought it was rediculous that the biggest size didn't fit my 4 month old! And yeah, they dont hold A LOT, but i would have really liked them had they fit.
Oh, and one more thing, I had to pin them because my snappi wouldnt hold.
