Happy New Year everyone.
crazy, DS still has all naps and all evening sleep in the sling at 11 weeks. DS1 was 3.5 months when he stopped needing the sling for all sleeps, so I feel reasonably relaxed, though I'll be glad when I can put him on my back! I tried putting him down this evening when he was fast asleep, but it was only 2 minutes before he woke again.
IME babies are affected really differently by sleep regressions/developmental leaps etc. DS1's 6 week growth spurt lasted a week and a half, but I didn't even notice DS2 having one!
debbie, must be something in the air - DS2 just wouldn't go to sleep this evening and was up for at least 3 hours (uncharacteristic - I think something I'd eaten might have been the problem as he has sensitive digestion).
princess, I find bf night feeds really easy. I'm lucky that DS2 is a fantastic sleeper and generally only feeds once each night. We co-sleep and I just stick a nipple in his mouth and go straight back to sleep. In fact, I've fairly often woken up in the morning thinking he's slept through, only to find he's on the opposite side of me from where he started, so I must have switched him over and fed him without even waking up properly. 
DS1 has been having an allergic reaction for the last 4 or 5 days, which I'd thought was a viral rash. It's good it's not anything like chicken pox, but I'm struggling to work out what could be causing it.
DH starts a new job next week so I'll have to do night duty for DS1 who at 3 years old has never routinely slept through the night. He and DH normally sleep on a different floor of the house from DS2 and me, so he'll probably be very excited by the change (he'd rather have me there than DH any day). I forsee a lot of waking...
