She's always been a bit picky but I'm starting to really worry about her eating habits now. She eats a nice breakfast of eggs, oatmeal, or steel cut oats, the rest of the day she refuses to eat. I think part of it is her babysitter just sets out snacks for her 4 year old so she is constantly grazing, I've ask numerous times that she not do that.

She will take 1 small bite of lunch and finer and be done. We can get her to take 3 bites of banana and she'll eat her greek yogurt. That is about it. We're thinking of giving her pediasure since she's not getting enough of anything.

She's very irritable, prolongs bedtime, whines and cries a lot.
Has anyone else gone through this?
