I hadn't been asleep yet. I fed him around 11pm, then he wasn't interested anymore at all, so I thought "we'll go to sleep". But then he was doing all sorts of grunting and not going to sleep, so I put him on the boob again around 12am: cue 45 minute boobing session 
Next wake up was 3.30am for about 5 minutes and a nappy change, and then.. wait for it.... 8.30am!! I'm still tired but the 5 hour stretch does make all the difference.
Off to a sling library soon! I love the Kari-Me but I find it a bit too stretchy and also such a faff to put on and take off. which I always end up doing more often than I think. Hoping to try maybe a woven sling, a part shaped one like a caboo and maybe something like an Ergo.
