Good luck today then Roller if you do get out! I find public transport tricky, stairs everywhere on the tube (and only 5 weeks post section can't lift pram by myself)and only one space in the bus, so have been using the sling, but it's tricky to get her in & out to feed, change etc while out & about!
Agree fl0 about the winding! but if you don't you know it'll bite you on the arse later - couldn't properly wind DD yesterday while out because she was cocooned in the sling insert and she was sick by the time we got home, I felt like such a bad mum. What I find does help is feeding, changing happy then winding - by the time she's laid down flat and been picked up again it kind of works it's way out more easily.
& Livvy you are by no means alone with the sleep deprivation! We had another 6 hours wide awake in the night, my child is nocturnal it would seem, so I get an hour or so before midnight and go back to bed at 6am for a couple. Hope I can reset her body clock, but I'm so desperate in the day I do tiptoe a bit, TV on sometimes though, curtains open.
Can I ask what people do about changing in the night? Do you feed and change in the semi-darkness to keep things quiet? I don't really have room in the bedroom to change her so end up taking her next door, but it's brighter and it probably wakes her up a bit more. Might see if I can create a changing area somewhere in the bedroom...
