if u feed your baby "real" food?

if u feed your baby "real" food how do you gage how much to give them?

for example:
i'm used to ds eating 3/4 stage 2 food so how do i know how much cheese and crackers he should eat?

i'm having an issue b/c ds hates eating b/c of relux issues so he'd never "ask" for more and i usually have to encourage him to eat, so i can't rely on him to let me know if he is full or wants more.

Re: if u feed your baby "real" food?

I have the same issues.
The reflux baby gets full quicker and never eats and eats.
I read if they eat 1 tbsp for every year they are that is ok.
It is better to have a reflux baby eat more frequently and small then alot.
It never seems to stay down if they eat alot.
