Chu Chu's training teat is compatible with this bottle.
The bottle is equipped with Chu Chu's Super Cross Cut teat. The opening of the teat reacts to baby's sucking force. It is opened only when it is sucked. So it does not leak or spill like round hole teats. This feature also enables that one teat fits all stages, purchase of teat is easier.
Because it is a standard neck bottle, strong sucking force is not required. It is suitable for almost all newborn babies. If your baby is both breastfed and bottle fed, and you find it is difficult for him/her to switch between them, then a bottle with training teat is needed.
PPSU is the best BPA free bottle material in the world.
