My son Charlie loved trying his Comotomo Baby Bottle. We liked the 5 ounce option as some of the other bottles could fill to 11-12 oz and he never took that much milk. Those larger, bulky bottles made it hard for Charlie to hold on his own. Just last evening I fed him before bed and he could one handed hold his Comotomo Baby Bottle and hold his puzzle piece in his other hand. I love the soft, breast like base but the sturdy upper ring that allows for ease of cleaning and filling with milk. Easily fits into our bottle warmer and simple to clean. Finally someone who gets that we want a bottle to be most like our breast and Comotomo has done it again.
