My 16 month will not sleep at night she not sick no fever. it been going on for five night what can i do for her?

You still need to : have her pediatrician assure you she's healthy. If so, at a consistent bedtime, read, rock, brush her teeth after the last feed. Put her to bed in her own room drowsy, but awake, to learn to self-calm to sleep without bottle or pacifier. Ignore night-waking. It will first increase, then stop. See graded ignoring tips on healthychildren.org if you can't consistently refrain from entering her room.
