I just wanted to recommend the app 'Baby Timer'. This has been indespensible to me since I brought dd home, & I still use it every day now she is 4 months! It enables you to log nappy changes, feeding & sleeping, as well as making other notes, & has been brilliant for seeing patterns etc. It also enables me to check when she last did everything, as I find this very hard to remember, & am often surprised by how much time has passed since the last nappy change or whatever. I know it might sound a bit obsessive, but I believe it's the opposite, allowing you to not stress at having to remember stuff. Good for checking which boob to feed from next too!
