I saw this bottle on my social media and thought it would be a nice solution to add more nutrients in my son's diet. Since he is not a big fan of milk I decided to give this bottle a tried. It has change our morning routine, he is happy having his smoothie on the way to the daycare and I am happy how messy free is this bottle. I am a big fan of it now and telling all my mamas friends about it. Only con is the duty fee, I'm living in Canada, but still, it worth 100% the purchase.
