A time includes everything from eyes open to eyes closed, so feeding counts as part of that. In the early days there isn't an awful lot of time for anything but feeding and a nappy change, but that will change quickly over the next few weeks. Are you breast or bottle feeding and how long is a typical feed lasting at the moment? Total A time at 8 weeks is typically around 1h15, maybe a touch less. If your LO is having significantly less awake time than that, then it might be worth gently trying to keep him awake a touch longer, but honestly this sleepy phase will be gone before you know it!
