So we have twin boys so our hands are full and one of them is a little piggy and cannot wait for his milk. He gets very agitated when the nipples get clogged and we have tried pretty much everything: Dr. Browns (wide & skinny), Playtex Ventaire, Born Free, and Tommee Tippee. He didn't like many of these and we hated cleaning and washing all the little parts and gadgets. We decided to try this cool looking elephant bottle and he loved it. It is simple yet effective and I like that it actually has a fun little design on it. We will be getting more. Bonus, our little guy can practically hold the bottle on his own now too!
