My Baby Is A Poor Eater :(

Well, she's 15months old, and her eating habit is really bad, maximum would be 10teaspoons of porridge that is if I'm lucky enough... If not then nothing... I've got no idea what to do with her, her weight is about 8.2kg ? Nevertheless, she is active and good at talking already... She drinks about 6onz milk (, 4 to 5onz per day, frisolac brand)
