My DD is 4 weeks old today and I'm wondering if I let her have too much sleep this afternoon? The rest of the day she had been going 3hrs in-between feeds (I'm breastfeeding) but she didn't wake up until nearly 5 hours after her last feed (even then I had to rouse her) Do you think this could muck up her nighttime sleep? She really fought getting to sleep after her 8pm feed and then woke after only 45mins. Since then I've been up for the last 5 hours trying to settle her, but she just keeps waking up after 20 mins screaming and gets herself into a right state. I know they say never wake a sleeping baby, but surely 5 hours is too long a gap for a LO?
