We loved the Yoomi Bottle with Slow Flow Nipple when we first got it for our daughter from a close friend! Is an expensive bottle, comes apart in 4 pieces so its easy to clean but a pain to put together and not leak! we only continued to use it for so long because my daughter loved it, but if the lid get screwed on wrong look out!
This product is okay. I just don’t like the fact that the nipple teat deforms when baby constantly sucks. And when it deforms, major leak happens.
