Help with baby’s solid food


Baby is 5 months old. Since one month my dr told me to put a on tea spoon or half tea spoon of bananas from gerber stage one in her milk

Now dr said she is ready for solids so I feed her with a spoon

Can I give her 2 oz of solids with 3-4 oz of formula? Cuz she usally drinks 5-6 oz every 3-4 hours! And sleeps 10 full hours at night..

I would ask my dr but she don’t always answer my questions. Or is it too much.
