Right now your baby should still be on breast milk or formula until he is one in addition to the solids.. It is hard for me to tell you exactly how much to feed your baby because that is going to vary from child to child based on his needs: weight gain and maintenance, activity level, and so forth. The best thing would be to ask your pediatrician and check his weight gain and length to make sure he is getting adequate food/balanced intake.

But i started her solid foods just after 6 months.
i've searched and found this at internet and started giving her according to this guide. Importantly 3 days gap between new food.

What to feed

• Breast milk or formula, PLUS
• Small amounts of soft pasteurized cheese, yogurt, cottage cheese (but no cows' milk until age 1)
• Iron-fortified cereals (rice, barley, wheat, oats, mixed cereals)
• Mashed fruits and vegetables (bananas, peaches, pears, avocados, cooked carrots, squash, potatoes, sweet potatoes)
• Finger foods (lightly toasted bagels, cut up; small pieces of ripe banana; well-cooked spiral pasta; teething crackers; low-sugar O-shaped cereal)
• Small amounts of protein (egg, pureed meats, poultry, and boneless fish; tofu; well-cooked and mashed beans with soft skins like lentils, split peas, pintos, black beans)
• Non-citrus juice (apple or pear)

How much per day

• ¼ to 1/3 cup dairy (or ½ oz. cheese)
• ¼ to ½ cup iron-fortified cereal
• ¼ to ½ cup fruit
• ¼ to ½ cup vegetables
• 1/8 to ¼ cup protein foods
• 3 to 4 oz. non-citrus juices

I'm a new mother; my daughter is 3 months old. I breast feed and I started giving her the Gerber 1st foods last week - fruits and vegies.

in the morning I give her half the fruit container and 4oz of milk.

through out the day I give her 4oz

for dinner I give her the entire fruit container and 4oz of breast milk or formula (the advanced soy infamil).

I'll know to give her more than 4oz because she will cry after a feeding letting me know she is not satisfied.

When she was drinking 2oz and was ready for 4oz, she cried until I gave her more milk. When she falls asleep towards the end of her feeding. That's how I know she's getting enough. And, if she falls asleep on that third ounce, I don't force feed that last ounce because 3 ounces was obviously enough.

so to sum it up, feed her until she falls asleep, Use common since regarding portions, and feed her baby food/table food at the same time twice a day so your baby has a since of morning and night - fruits for breakfast and vegies for dinner.

thanks atlanta206 for for response

My daughter is now goin to be 10 months old soon. but she still drinks 4 oz of milk. i give her banana shake in mid morning the boiled egg yolk mixed with cheese in lunch and mashed farleys biscuits with milk in evening and cerelac or any other meal in dinner. At times some other cereals as well. In total i try to feed her 23 oz of milk in 24 hrs. i dont know if its still not enough for her as she doesnt look like i was in my childhood. i mean healthy and chubby. but shes very active and smart.
