I boiled my bottle for a long time, is that ok?Updated a year ago

Silicone can withstand high heat, the max heat is 180℃ / 356℉. Boiling your bottles for a little longer should not cause any issues in quality. 

That being said, we do recommend keeping an eye on the water level while boiling. The water can evaporate causing the bottle to touch the hot surface. If there is no visible damage to the bottle, it should be good to use.
