Cherub Baby Wide Neck Glass Baby Bottle * NatriBaby Bottle with Color Changing Technology & Shock Absorbing Silicone Sleeve * Lightweight * BPA Free * Safe - 5.1 oz. Orange

I've been using these bottles for 4 months now. What I love about these bottles is the flow. Compared to other bottles the flow is somewhere in the middle, not too fast where the baby chokes or too slow. My baby ends of drinking more milk from this bottle than the Joovy Boob. Because she has to suck harder to get milk out of the Joovy Boob bottle, she ends up drinking about an ounce less. I only breastfeed at night so it doesn't bother me if my baby's suckle is not very hard. If you exclusively breastfeed and use a bottle infrequently, than I do not recommend this bottle for you, otherwise your baby may get lazy and stop sucking so hard. The Joovy Boob bottle is great for those mommies who exclusively breast feed and use a bottle once in a while.One problem with the Cherub bottle is that sometimes the nipple moves around a little while my baby drinks. This didn't start happening until just recently, but it happened with all my Cherub bottles. It is quite annoying but it isn't a deal breaker for me and I would repurchase this bottle for the reason that I like the flow. I did take off a star for this quality problem. The Joovy bottles are solid and there is no issue with the quality of the bottle at all.
