My first child failed to drink water from every single kind of sippy cup I bought 😂 She just couldn’t suck it out. Only managed with straw cups and later on normal cups. The pigeon one you showed is a progressive cup, like an all-in-one cup that grows with your child, so you can start using it earlier. The Phlips avent one.. material’s okay. The mouth needs to be a bit bigger to create a good seal.
