When my baby is eating solid foods, what type of dishes and utensils should I choose?

When he has become good at eating with his hands, let him learn to feed himself with a spoon. Pigeon recommends a spoon that is about 2/3 the width of your baby's mouth and not very deep.
At this point, a fork is still too dangerous. You can start your baby using a fork from about 18 months. For drinking water, the best cup would probably be one with a narrow rim and handles, so he can hold it and drink it himself.
