Very Convienient!

I used these liners when my son was a baby; I really enjoyed how convenient they were. I could just change the liner when my son needed a new bottle and I didn’t have to worry about sterilizing a new bottle. I used other bottle liners that I had to fit over the bottles. These you’re just open up, and drop right in. The sides of them say the proper measurements for the liquid and you don’t have to worry about not being precise. These are a little bit pricier than most fills for the Playtex bottles, but I really like how easy they are to use and fill up. I have used the smaller as well as the larger ones. I also like how the bag collapses as the baby drinks; this makes it so there is less gas going into the baby’s tummy. We all know babies who are less gassy are easier! I have recommended these to other mothers and I even donated some of mine that were left over to a friend, she loved them so much she bought some herself. The drop ins are made of a thicker plastic than most fills for disposable bottles.
