Replace inner straw with silicone
Great! Just need to replace the inner plastic straw with a silicone one, because Science. Luckily you can do that yourself! I got ours from GoSili and their shortest straws fit perfectly at about 5”

perfect for toddler
Our 1 year old uses these water bottles and prefers them because they don't have the check valve in most toddler cups, making it much easier to drink out of. They're pretty spill proof, even when open, for the most part if you have the straw piece fully popped in and the water bottle isn't overly full.

Good size. Fit in car seat cup holders!
Good size for small hands. Top closes securely and button is not too hard for little fingers. Haven’t leaked when closed yet and we’ve been using them for a few weeks. My 5 and 2 yo figured them out quickly. Straws bendable on top and cleanable with bottle brushes. They fit in car seat cup holders which is a big win. Curious to see how the plastic lid and design hold up to frequent washing. Great size for id say up to 6/7 and then may be a little small depending on how thirsty your kids may be.
