I have been looking for a water bottle for my 3 1/2 year old that wasn't a straw kid's cup, but that wasn't too big for him (some of the ones I was looking at were too large, a bit complicated or I was afraid he would chew through the straw if he had to bite it to get the water out).
I was in Target last week, and I decided to checked out their water bottle section (by the outdoor equipment, etc.) and I found one that was BPA free for $3.99, it is called EMBARK.
It wasn't until I got home, that I decided that I liked it even more! My older son was so excited about the water bottle because it looks similar to my husband's Nalgene. When we opened it up, we realized that the water bottle is 2 step. It has a straw that goes down in the the water bottle for younger kids so all they do is suck to get the water out OR for older kids, you can take the straw out from the inside and they can turn the water bottle up to get the water out. The pop up "straw" cannot be chewed through (YAY!) and goes down when not in use.
Well, we had to go back to Target because Brody had a meltdown that his brother had one and he didn't (oops...I didn't think that it would work for Brody, but it does because it is 2 step). Both boys have one now and we put their Bumpyname Orbit Labels on it (different colors) so they know which ones is theirs. My older son uses his without the straw inside and Brody uses the straw. PERFECT! They can even go in the top rack of the dishwasher.
I fill the water bottles up every morning with water, add ice and set them out so they can drink whenever they want. I am very excited! It was well worth it... $8 for both boys; if they don't last for a long time, we are not out that much money. Plus, it is a fun way to encourage them to drink water.
Get yourself a water bottle too and fill it up throughout the day. I like to add fresh lemons to mine. Model good health for your children. It starts with us :)
