Hi Hollo, congratulations on your precious little daughter
Please don't stress too much about the "Feed, play, sleep" routine that is commonly recommended. It does work for some babies, but many others have all different routines (or no routine at all) and they almost all grow into happy and healthy children. We almost always fell into a "Feed, play, feed, power nap, more feeding, sleep-if-we-were-lucky" sort of thing. Also their total sleep requirements vary a lot. I have read that babies "should" sleep up to 20 hours in the 24, but I have never yet met any baby who slept that much. My first child slept maybe 15 hours in 24 as a newborn, my second never slept much more than 12 hours. As long as she's healthy, she will sleep as much as she needs to (although it may well not be in a pattern that suits you!).
