My newborn is 6 days old and has been regularly sleeping for 4-5 hours. She's currently still asleep, last feed was at 6am. I've read that I should wake her but don't feel right about it. My husband and I are good sleepers and my mum said I was like this as a bub. I'm worried that of she's tired she needs to sleep but also want to keep up demand for my milk. Any advice? If waking her is the best solution I will do it.
