Question!

How long does your baby breastfeeds for? My baby is 8 days old and she feeds for 20 minutes on one side however when I switch her to the opposite she feeds for a couple minutes like 10 minutes then falls asleep. I wait a while burp her and lay her down then she decides to wake and cry because she's still hungry within 5 minutes of laying her down. Help! Any suggestions? For example I'll feed her at 2:00, then burp her and switch her to the other side by 2:20 and she'll feed till 2:30 - 2:40 on the other side and then I burp and lay her down and then it'll be a battle where she keeps waking up and it's not until 4:30 when she's satisfy.
