We've tried several bottle brands and while there are plenty of good ones out there, only one actually met the standards we needed for traveling with a baby in an RV.
And the winner is Tommee Tippee Closer to Nature!
Tommee Tippee Closer to Nature bottles have the option of convenient formula dispensers.
This is so helpful and saves so much time and space! Who wants to hear a baby crying in the middle of the night while you fumble for a formula can while rolling down the highway? Not me. The formula dispensers fit inside each bottle and keep the formula dry so that you can pre-fill the bottles with water. It's so much easier to prep a bunch of these ahead of time and then use a wet bag to store the dirty ones until the next washing.
The associated parts are simple.
Taking apart bottles for washing can sometimes be crazy. Some of them have ridiculously shaped parts that are impossible to clean, which makes them even more impossible when traveling in an RV. Tommee Tippee Closer to Nature bottles are just the opposite. Even when you add accessories, they're easy to take apart and easy to clean. This makes them much more convenient when on the road. Some of our favorite accessories include the variable flow nipples, the formula dispensers, and the bottle handles.
The price is considerably low for the convenience they provide.
When you factor in all the conveniences offered with the Tommee Tippee Closer to Nature system, the price of stocking up on them is lower than some of the other brands but with more convenience. Even when the price is fairly comparable to other major brands, those other brands don't seem to offer the same conveniences. So, why pay that price to get something that's less than stellar? We don't. We only use Tommee Tippee Closer to Nature bottles in the RV (and elsewhere) now.
