Tommee Tippee the closer to nature bottles I started using when my son started drinking more then 4 oz at a time I have to say I am in love with these bottles there so simple yet so great my son took to them really well. These are the closer to nature 9 oz ones in blue with the pattern of the sail boats. About the bottles.

At first I thought he would have a hard time with the nipples being so soft. But he took to them and I love these bottles and Tommee Tippee if your looking for a great product for switch from bottles to cups too. We will be doing a review on that in the future.
