My lo seems to need to feed very regularly for part of the day before going for longer later. It is very tiring as I can start a new feed every 30 mins or so, lasting 15-20 minutes. There is no time for me to do anything in between. I do put her down, but crying soon ensues. DH says to just let her cry, but at 3 weeks old, I don't like doing that. So far today she has had 12 feeds in 10 hours ranging from 10-22 mins when she unlatch es herself and won't go back on. Is this normal? Even when she goes longer, 2 hours is usually the most time between.
