My 1 year old refuses to eat?

My 12 month old daughter refuses to eat anything except cheerios, yogurt bites and puffs. She is in feeding therapy but I want to know from other Moms. She has almost starved to death (sent to PICU) because she wont eat. She gets pediasure once a day right now (it can be 2 a day but I can't help but wonder if this is filling her up too much). she used to try things, now she refuses everything. she hasn't eaten ehough to fill her stomach (without the pediasure) in over a month. I don't understand, is this a battle of wills? Her FT wants me to make her a varitable banquet and stand on my head to get her to eat it she just throws it on the floor or turns her head away. All she does is through it on the floor. Please help, I am so afraid and frustrated. Oh, she is on all the meds she can be on for reflux.
