My 18 months old Son recently seems to be drinking too much. From 7pm to 11pm, he had drank 3 bottles of milk, each 270ml! And he had rice at 7.30... Is that too much? But If i dun give it to him he will cry & shout. What should I do?

Agree with the mommy above -- perhaps you can try cutting down on the amount of milk per feed. That way he can have the additional serving of rice. As long as your baby keep within his daily caloric intake -- there isn't anything to worry about; he's a growing boy :)
