DD is 8 weeks old and has been exceptionally sleepy today. She's usually quite alert, but has spent most of the day asleep. I have woken her up to feed her which I didn't usually have to do. Has had one small dirty nappy and 3 or 4 wet ones so far today (breastfed, so it's not unusual for her to have some days with minimal poo, and some days with lots) No temperature, no excessive crying.
Should I be worried, or just enjoying the peace and quiet?
