If you ever end up giving your babies bottles, let’s face it, you’ll have double of them. Double to make, and double to wash. I absolutely adore the Playtex Nurser Bottles for lots of reasons, including the fact that you NEVER have to try and scrub out the bottle! Just take out the used liner, and throw it away! It’s SO worth it. It also means carrying less bottles with you when you’re on the go, without having to worry about finding a place to wash them out. If were going to be gone for 4-5 hours, that could mean at least 4-6 bottles we would need to give the babies. Instead of having to take that many bottles with us, we only needed two! We could just bring as many liners as we needed, and we were good.
