The best non-toxic sippy cups for your littles

I’m a huge advocate for non-toxic everything, especially when it comes to my littles. So for sippy cups, I don’t have a big list because there were really only two brands that made the cut. THINKBABY and Pura.

After doing a lot of research, I discovered that  “BPA free” is literally a government requirement for all sippy cups. There are actually so many other chemicals that are in plastics that can do just as much if not more damage as BPA.


  • That being said here are the deets on the two options:

    1. THINKBABY sippies are plastic, but they do not utilize any of the known carcinogenic, reproductive toxic, endocrine disrupting, neurotoxic materials in their products. The list is extensive, but they are mindful (and I love it) they don’t use:

    No alkylphenols, polyurethane,
    No petroleum distillates,
    No phosphates,
    No chlorine
    No chlorinated or brominated solvents
    No petroleum-derived or petrochemical fragrances,
    No parabens,
    No sulfur oxides,
    No organohalides,
    No formaldehyde,
    No trichloroethylene (TCE)
    No perchloroethylene (Perc)
    No dioxins and furans,
    No hexavalent chromium,
    No organophosphate pesticides
    No polybrominated diphenyl ethers (PBDEs)
    No di-(2-ethylhexyl)phthalate (DEHP),
    No 2,4, dichlorophenoxyacetic acid (2,4, D)
    No toxic dyes
    No PVC
    No PET or copolyester
    No Melamine
    No Bisphenol-A (BPA)
    No Bisphenol- S (BPS)
    No PFCs
    No Formamide

    The nipple is very bottle like (and makes for an easy transition from bottles) and the handles really help the littles figure it out. It’s a great option for transitioning from bottles. They are dishwasher safe too.

    2. Pura sippies are all stainless and medical grade silicone (so no plastics) and they are non-toxic certified.
    Their product materials are screened for all known carcinogens, endocrine disruptors, reproductive toxins, neurotoxins, behavioral toxins, flame retardants, heavy metals, pesticides, insecticides, herbicides, toxic solvents, harmful VOCs, or GMOs. Their testing process also aims to close data gaps by screening each material and ingredient for persistence, bioaccumulation, and general and aquatic toxicity.

    These are great because all tops fit all bottles (we have gone from sippy top to the straw top and even the regular bottle top, while only having to switch out the tops). My daughter loves that we have the same water bottle it makes her feel like a big girl. They are also dishwasher safe.


For transitioning from bottles to sippies, it's easier to do the switch in two parts. First with water at around 9 months, then for all other liquids at 12 months in one week. We just replaced one bottle a day for a week, and never looked back. Then at about 18 months we started the transition to the straw sippies, and that took some learning, but she still used it in the car and at daycare (at two years old). Hope this helps, if you have any other cups you trust, I’d love to hear what works for you!
