Playtex Drop-Ins Original Nurser Baby Bottle Review

i love these bottles. I was using the dr.browns bottles and still my son spit up a lot. I got one of the playtex drop ins bottles as a sample in the mail and i started using it and my son hasn't been spitting up at all. Im hooked on them and defenitly would recommend them i thought they would be hard to use because of the liners and everything but they are very easy to use.
