How much feed? --- give as much as baby wants self demand, grand mothers' idea. How long ? At least 6-8 months exclusively on breast feeding. Then think of weaning Give breat feeding not pump ed breast milk.

Babies should be fed exclusive breast milk till 6 months of age. Baby should gain weight of 200gm a week, pass urine and motion. That is more important than quantity of milk. Also weight of baby can be used to calculate amount of milk needed. Aim to give about 160 ml per kg per day divided every 3 hours (8 feeds ). So if weight is 4kg, give 80 ml every 3 hours. But weight gain is more important than quantity.

Greetings , baby should be feeded for 20-30min per side /each feed give every 2-2.30hrs on demand burp the child for 10-15min
