DS1 is 10 wks today and is going a very consistent 4 hours between feeds at night. Down at 7.30pm, awake at 11.30/12, feed, awake at 3.30/4am, feed, awake at 6.30/7am. He's good, he'll take a feed and then settle straight back to sleep but he's been doing this for about 5 weeks and I guess I'm waiting for something to change.... We actually had a few 5/6 hour stretches when he was 4 weeks and thought we'd hit the jackpot but that lasted a couple of nights. And then at 6 weeks he started going to 12.30am....but we're back at 11.30pm. He's breastfed and a good weight, on 50th centile.
