no suction

have ordered the dish because I thought she holds at the table when our son eats itself something small ... but after 30 seconds. allows the suction to and he can throw down the dish .... but it is not at the table ... have tried it on different surfaces, even on the working surface of the kitchen ... and no ... it does not stop !!! ; (
Well, they take now to stop feeding porridge .... in the micro to the micro-cap because it's super. Discolored it has unfortunately already slightly (carrot) ... but that's usually the case with Plasik.
