My 3.5 week old tends to wake during night on the 3 hourly mark (often under), however once fed, winded and changed she can take a further hour + to settle back to sleep as she is wide awake so she doesn't actually go the full 3 hours sleeping. We keep lights off (have a feeding night light) and try to reduce any stimulation but she still seems to not want to settle back down. Last night it took 2 hours after the first wake up to get het back off to sleep. She does have bad gas which may impact on it. She us breastfed, i think we may also be having problems with fast let down as she has recently been ''thrashing' during some feeds (more so on an evening and night). Any advice?
