10 day old sleeps a LOT

[Happyface82]

Should I be worried? She only wakes up in the early evening - late evening. So far she's putting weight on fine (exclusive breastfeeding). Somehow today she hasn't fed much and hasn't really stayed up yet at all. Has only woken up to feed. Is this normal?

Sounds a little like mine - 16 days old! She comes awake in the evening and is a dream during the day. It's to do with them not distinguishing between night and day yet but I was told to not let her go more than 3 hours without a feed so wake her up by a change of nappy/undressing her then BF. If she falls asleep feeding, I wind her and then re offer as she normally wakes back up during winding x
