Our lifefactory bottles have been with us everywhere since we got them - walks, meals, road trips, and the pool (oops). They are so easy to use even my 2 year old figured it out within minutes. He was pleased to have one "just like mama". Try as he might to break it, his little blue bottle has proven it's strength. We recently started our 7 month old with the sippy version too, and it has survived trips off the high chair without damage. I enjoy sipping from mine daily to get my H20 in and am glad to know that the lifefactory bottles can handle our day to day challenges.
