Review on MAM Easy Start Anti Colic 5 Oz Baby Bottle, Easy Switch Between Breast And Bottle, Reduces Air Bubbles And Colic, 2 Pack, Newborn, Matte/Boy by Rhonda Green

Daughter started taking a bottle at 4 weeks, used the Medela bottles that came with my breast pump just fine. Then at 6 weeks, she up and decided those weren't good enough anymore. And so began our hunt for the perfect bottle.During the following 3 weeks, we tried all of the below brands:- Comotomo- Dr. Brown's- Medela Calma nipple- Munchkin Latch- NUK First Essentials- NUK Perfect Fit- NUK Simply Natural- Parent's Choice (Walmart brand)- Phillips Avent- Playtex Nurser- Tommy TippeeThe Picky Princess would occasionally latch on the NUK Simply Natural and the Comotomo, but not with any consistency. She flat out rejected all of the others. Then FINALLY I came across the MAM and tried it out. Instant success! She's used this bottle successfully for the last 8 weeks.What I like:- The shape of the nipple is short and flat, unlike any of the other bottles I tried. I'm convinced this is the reason my daughter was able to latch to it successfully- The self-contained sterilizing feature. Very convenient to not have to use steam bags or a big plastic sterilizing tub.- The anti-colic functionality. When my baby sucks on the bottle, you can hear the bottle working its magic. She's no gassier using this bottle than when she breastfeeds- The measuring cup in the lid.What I don't like:- There's a lot of pieces. Not hard to clean, but not as easy as other bottles out there- If you don't assemble all the pieces correctly, it can leak, though this has only happened to me once so far, and it was 100% operator error- The bottom part of the bottle isn't transparent and doesn't have volume markings on it. The lowest volume measure is 2oz, which makes it hard to tell how much is left if the baby doesn't finish the whole bottle.- Because the anti-colic system is located in the bottom, it makes it hard to use a steaming bottle warmer. I end up just heating the milk in my Medela bottle and then pouring it into the MAMOverall, I love this bottle because my daughter loves this bottle. MAM has clearly put a lot of thought into the anti-colic system and the self-sterilizing function. Putting together all of the pieces is a mild inconvenience, but worth it because my daughter drinks out of this bottle. If the MAM Easy Active bottle was available in a smaller size, we probably would have gone with that, because I'm convinced it's the shape and texture of the nipple that got my daughter to latch onto it.
