Whenever we try to feed any liquid to (both of) our 14-month-old twin girls, they cry. This includes milk, water or any kind of liquid. They don't use a bottle anymore, so we are using a spoon to feed them.
We have tried various positions like: putting them on their booster seats, making them sleep on our laps. No change; they cry. However, they don't cry when they are fed solids. Is this normal among babies? We are clueless how to control them.
Any suggestions? Should we visit some kind of doctor?
