  • How is the thinkbaby Sippy cup different?
    Most of the sippy cups on the market have hard plastic spouts or rubber spouts. We built the thinkbaby Sippy Cups with soft silicone spouts. This makes for easy transition from baby bottles to sippy cups. This is a struggle that most parents face in moving to the next stage of feeding. With the thinkbaby Sippy Cup, the little one is already used to the feeling of silicone so making the transition is quite simple.

    The spouts also feature a cross cut design so they do not spill when held upside down, which obviously happensquite often. There are also next extra little pieces to lose or clean.

    The Sippy Cup has won numerous awards for both the ability to transform the baby bottles into the Sippy Cup and for the ease of transition from baby bottle to Sippy Cup.

    The Sippy Cups are made from No. 5 plastic and therefore can be recycled after use. You may also notice that we do not use clear plastic windows with our products. We have found that these windows are made from PET or PVC. It doesnt make sense to take a safe baby bottle and put it up against something that can off gas onto the product.

    How do I convert the thinkbaby bottle into the Sippy Cup?
    One of the great things about the thinkbaby system is that you can convert the baby bottles into the award winning Sippy Cups. To convert, remove the baby bottle nipple and replace with the Sippy Cup spout. Then place the Sippy Cup handles around the top of the baby bottle and push down over the neck of the bottle. Tighten the collar with spout around the neck of the bottle and presto you have the thinkbaby award winning Sippy Cup!

  • How do I care for my thinkbaby Sippy Cup?
    baby Sippy Cups are dishwasher safe (Top Rack recommended). Please take care not to wipe the measurement markings. We do not use lead in our paint, which is what predominately makes paint stick. The US and EU standards actually allow for low levels of lead. We specifically do not want lead in our products.

    When washing the baby bottles in the dishwasher, we recommend using a detergent that is free of chlorine. Most of the natural detergents on the market from Eco Lever to Seventh Generation should be free of toxic chemicals. If hand-washing, the American Pediatrics Association suggests using warm soapy water, but only if you live in an area with treated water systems.

    Before first use:
    We recommend sterilizing the bottles in boiling water for 2 to 5 minutes before first use. We do not recommend utilizing sterilizers, as we cannot guaranty that the ones on the market were made with safe materials. While the baby bottles are technically microwave safe, we strongly suggest that parents do away with the use of microwaves for all items and products destined for your little one.

    To prepare the nipple for first use, please squeeze the top of the nipple and the venting tube. You will want to make sure that both open properly. When tightening down the collar of the bottle, do not over tighten, as this will reduce the amount of airflow into the baby bottle.
