Smoothie = Very Cold Monkey

So, I've been making the 3 of us Green Smoothies in the morning. Basically, it's a fruit smoothie with dark leafy greens in it to get all the yummy benefits of them without having to have a spinach salad every day. Plus, I've never had collard greens before, but I've heard they're good for you. It just tastes fruity, but looks green. Kyle and I each drink about 16oz. and I give Maddox about 6oz. Any way, today, Maddox is sitting on the kitchen floor drinking his smoothie and I look down and his lips are blue and his jaw is literally quaking. Poor guy!
