My soon to be 6yr will not eat.

Any advice??

My daughter used to eat waffles, pancakes, toast, eggs, hash browns, pizza, hotdog , spaghetti, rice, chicken etc. now she barely eats at all. This has been going on for a little. Before she would eat 2 waffles. Now she barely eats one. She says she’s “full” she LOVES chicken but now she doesn’t even finish it like she used too. She uses the bathroom regularly and is not constipated. She drink water and juice. 

I don’t know what to do i tried everything even bribing her if she eats this I would give her her fav ice cream and nothing! I just want my baby to eat.
