Trendy tots sip from stainless steel bottles! New mamas looking to bypass the plastic bottle drama have other shatter-resistant options than glass. Earthlust's Birds & Bees stainless steel bottles ($24) are eye candy. Insulated to keep beverages cold or warm for up to four hours, the containers are designed to grow with tots, coming with pieces to transition from a slow-flow bottle to non-spill sippy cup. Like Earthlust's grown-up water bottles, the Birds & Bees collection is BPA-, PVC- and phthalate-free, making it a safer choice.
