What to do when my baby sucks air?


When your baby sucks air from the cup you can try one or more of the following actions.

  1. Check the drinking hole in the spout on potential blockings.
  2. Check the valve. Two openings in the valve must be checked. The drinking hole (in the middle of the valve) and the air slit to let air entering the cup while drinking (small block at the inner side of the valve).
  3. After assembly, slightly unscrew the screw ring (only one centimeter). Then tighten the cup again. Make sure that the cup is not closed too tight. This is to settle the valve correctly in the ring.
