Bertil Bottle is recommended for older children. Kindly note that chewing on the straw (drinking spout) will leave marks, and there may be a risk of the silicone surface being bitten off entirely. To reduce this risk, you may remove the silicone portion entirely to reveal the plastic drinking spout below, which does not affect the usability of the bottle.
Bertil Waterbottle can hold both hot (up 12 hours) and cold liquids (up to 24 hours). It is a leakproof bottle that comes with a regular and activity lid.
