Title: Not really satisfied with the product
Review: My review focuses more on the practical aspect of the sippy cup than the way it's made. I don't have a problem with the design or color, it's just that somehow the air is not flowing as it should and as the baby sucks, the nipple shrinks in and you need to open the lid and let air go in so the nipple gets its form back. Maybe I need to poke the little hole that it has on the lid and make it bigger...
