Query: Suction does not work

I was very excited to get these bowls in the mail because they are so cute, and the concept of having a suction bowl was (and is) appealing to me. My son loved the bowl right away, as he was able to reach into the bowl for some puffs to feed himself instead of having to push the puffs around the table until he could finally grab one in his fingers. I'd also like to add that he ate tofu cubes for the first time out of this bowl and loved them! However, I'm disappointed because the suction on the bowl does not work for more than a few seconds. I'm constantly pushing the bowl back down, which is disruptive to his meal. Despite some of happy memories I've had with this bowl, I would not recommend buying these bowls because as 'suction bowls' they do not serve their purpose.
