A baby gives new parents enough to fret about: Is she sleeping well? Eating enough? Pooping properly? Who needs the added worry of whether the bottle she's drinking from is releasing the endocrine-disruptor chemical bisphenol A (BPA) into her formula or milk? Parents who want to prevent this ingredient, a probable cause of brain disorders and behavioral problems, from disrupting baby's delicate systems should take care to choose BPA-free bottles from the get-go. No time to research which is right for you? We've swaddled up the best of the BPA-free bottles out there in this handy guide, to help keep baby healthy and mom and dad happy.

What: Babylife Wee-Go Bottle
Why we like it: You can't go wrong with the safest material out there—glass. Silicone holders provide your little one with a good grip.
Eco factor: The bottle, silicone sleeve, and nipple are nontoxic; the plastic cap and ring are polycarbonate and BPA-free, FDA-approved, and recyclable.
Where to get it: Babylife
Cost: $12 per 4-oz. bottle, $18 per 9-oz. bottle
Busy moms should know: Both the glass bottle and silicone sleeve are dishwasher safe. To cut down on those spills, the Wee-Go comes with a plug for traveling.

What: Born Free Bottles
Why we like it: Inner valves and air vents on the nipple help prevent colic, while still letting you shake the formula without side leaks or spills (as long as the cap is on).
Eco factor: The bottles are made of PES (a polymer that includes no BPA), so are less likely to attract chemicals from dishwashing detergent.
Where to get it: Newborn Free
Cost: $20 per pair of 9 oz. bottles, $19 per pair of 5-oz. bottles
Busy moms should know: Born Free's line is dishwasher safe and includes a cap. Born Free's bottle's have a low "vacuum level," meaning it's easy for baby to drink—but also easy to spill.

What: thinkbaby Bottle
Why we like it: Side grips make it easy to hold, while the anti-colic vents are built into the nipple. Plus, a conversion kit turns bottles into sippy cups as Junior grows up.
Eco factor: Bottles are free of BPA, phthalates and PVC, nitrosamines, and lead; plus, they're packaged in recycled paperboard.
Where to get it: thinkbaby
Cost: $17 per pair for 9-oz. bottles, $16 per pair for 5-oz. bottles
Busy moms should know: Built-in vents mean fewer pieces to keep track of; the bottles are dishwasher safe and include a travel cap.

What: Adiri Natural Nurser
Why we like it: The bottom unscrews so the bottle can be filled upside down—the nipple is molded to the bottle—and a long cap keeps the whole container clean.
Eco factor: The cover, core, and cap are made from BPA-free plastic; none of the parts include phthalate plasticizers, latex, or vinyl chloride.
Where to get it: Babies 'R' Us, Right Start, Whole Foods stores
Cost: $13 per bottle
Busy moms should know: Warming the bottle by submerging it entirely can cause leaks, unless you buy the separate warming cap.
