The transformational Thinker System line allows parents to transform baby bottles to our award-winning Sippy Cup through the purchase of the Conversion Kit. The system saves parents money and the environment from discarding baby bottles when its time for the next stage in feeding.
Dishwasher safe (Top rack recommended).
Before first use, we recommend sterilizing the bottles in boiling water for 2 to 5 minutes. We do not recommend utilizing sterilizers, as we cannot guarantee that the ones on the market were made with safe materials.
To prepare the nipple for first use, squeeze the top of the nipple and the venting tube. You will want to make sure they 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.
What nipple flow should I use?
The flow rates are determined by averages. Depending on your little one, you may need to adjust the flow rate that you purchase. The chart below should provide help in determining which to purchase.
Baby bottle nipples and spouts made from silicone will typically last 2 to 3 months prior to needing replacement. If you notice tears or breakage, discontinue use and replace.
How does the venting system work?
The venting systems work by allowing air to travel back into the baby bottle. Movement of air back into the baby bottle allows the bottle's internal pressure to reach equilibrium. This reduces the amount of suction required to get fluid out of the baby bottle. Research shows that having a venting system reduces the incidence of gas and spit up, as children take in less air when drinking when venting systems are present. The advantage to Thinkbaby's system is that it is built right into the baby bottle nipple. So, there are no extra parts to deal with and it's easy to clean.
How do I convert the Thinkbaby bottle into the Sippy Cup or Straw Bottle?
Remove the baby bottle nipple and replace with the Sippy Cup spout. 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-chango! You have our award-winning Sippy Cup!
Converting The Sippy Cup into The Thinkster: Take the collar off of the baby bottle (along with spout) and screw on the Thinkster top. Ta-da! The Thinkster!
