I personally is a huge fan of Medela products be it the bottles, pump, storage bags etc. Medela feeding bottles are super-easy to wash & clean and are very portable to carry. The added advantage is you could pump in these bottles directly and use them to feed at the same time, avoiding the hassle of double cleaning. I exclusively pump and these bottles have reduced my work to half. Because of their sheer quality, I would recommend Medela to anyone looking for baby feeding bottles. Thank YOU once again Medela!
