I have a 5 day old daughter..I breastfed my first but she was always hungry and fed from both sides so this didn’t apply! My daughter tends to feed from one side around 15-20 mins and then fall into a really deep sleep. I’ve tried changing her nappy etc to wake her and offer the other side but she either won’t latch or just sucks for a few seconds and falls back to sleep. Is this ok? She’s gaining well (lost 2% birth weight today as opposed to 4.5% on day 3). Should I just alternate a breast per feed or will only feeding one at a time like this affect my supply?
