My twins have been using these Thermos Funtainers for a month now and we have been loving them! They struggled with other straw cups until we finally tried these out. Now my kids drink out of regular straws with no problem which makes thing easier when going out. The are insulated and intended for cold drinks only. We do use them for warm milk, but I make sure it is never hot. The slim bottle makes it perfect for carrying in my diaper bags which is a plus. They are easy to find and not too expensive. It holds 12 oz of liquid which is great for my always thirsty kids.
You can these at Target, and a lot of places, I will add a link to amazon below:
Thanks for watching! I would love to know what cups you recommend for toddlers!
