Try a sippy cup as at 16 months he may be ready for one, put some milk in it , as long as he is getting plenty of food and water dont worry about any other drink,water is the most important liquid,milk is good if he will take it, give him finger foods, cereal, yoghort and his own spoon, fingers of toast with a little butter and jelly, egg, noodle soup at lunch time, those spaghetti meals with letters and animals in are fun, cut up chicken into small pieces. Let him eat by himself , they love it, better than being fed. Little fingers can pick up peas and beans, and some children love the brocolli florets!!!
