I'm breastfeeding exclusively. My DD suckles for 20 mins on each breast then falls asleep. I burp her and wait for her to settle before putting her down. She is asleep for 1 minute then wakes up crying and rooting again to feed. I always let her latch back on. This goes on and on so in the end I end up breastfeeding her for 3 hours at a time and she never seems satisfied. I'm producing enough milk as I can hand express plenty. Where am I going wrong? It's getting uncomfortable now. Makes it difficult to be able to get enough food and drink for myself.
