My baby has acid reflux since 3 months and anytime I give her finger or soft food she throw up before it goes in. so I only give her liquid food like first stage food.
:(
But I want to know if she is taking enough?
She is 24LB and 30inch tall - 18months old

She eat 24 oz soy milk only
6oz of vegis
5oz of fruit
6oz of rice and beans (again liquid blend)
6 spoons of cereal

Is this enough?
Any suggestion on acid reflux or food

Is the soy "milk" or soy formula? Since she isn't eating a great deal, you may want to consider the soy formula for awhile longer for the additional nutrients.
I am wondering if something else is going on since she is keeping the milk and puréed foods down. Have you tried just putting some soft textured foods/finger foods on her tray and let her pick at them herself? Maybe try it without actually offering them to her on a spoon... let her experiment with handling them and instinctively putting them in her mouth.
Some babies can develop an aversion to finger foods or textured foods if their first experiences are to gag on them and it can take some time and patience for them to be comfortable trying it again.
