I understand what you are saying and can see clearly why it would strike you this way. I don't think anyone here was saying that the OP is intentionally neglecting her child.
But that doesn't mean the child isn't being neglected, nonetheless. And from the description of the small amount of food this little girl is allowed to eat, I'm afraid I have to agree. Like pps, my kids ate far, far more at the same age.
I can understand how it might be very painful for the OP to even contemplate that the restrictions she's placed on her daughter's eating might qualify as neglect. But OP, I hope you will consider it, and consider taking the advice offered here and give your daughter enough to eat.
