I purchased these bottles from Amazon for on the go. So far they are holding up pretty good. They have not leaked and cleaning is easier than what I was expecting. You will need to make sure the nipples are completely dry otherwise the formula will clump and stick in the top of the nipple and that’s no good. Extremely easy to use and great if you have a bottle fed little one in daycare. The downside is that they are very expensive.

Some friend recommend me this for my baby and this is the best when you are about and the baby is crying is so fast to mix the milk.

I don’t know what I would without these, my favorite this so far ! Very simple and handy, I would suggest using a sanitizer with a dryer to completely have these dried when cleaned
