Advice pls! My child does not want to eat or drink plain water. She has been waking up in the middle of the night and keep crying. What can I do?

How old is your child? If your child does not normally wake up in the middle of the night, you may want to check whether she is feeling sick or feverish. If she has a sudden lost of appetite, it may be sign that she is feeling unwell. Check her temperature and symptoms of sickness. Bring her to see doctor if necessary.
