Hi hon, these things are always and in the first few months and your LO is still so little. I'm not sure from your post whether you are BF or Ff but if he's falling asleep on you, then maybe read this thread for some tips:
Tips for Sleepy NewbornsAlso, after he finishes a feed perhaps you can stir him with a nappy change or similar and then have some short activity time before beginning wind down to sleep. At this age you would expect an LO to be awake for approximately 1hr to 1hr15 mins and this includes the feeding time, nappy changes and wind down.
If you can avoid feeding him to sleep at this stage you will help him into some really great independent sleep habits, but if it's not possible for now and you think he's getting a full feed before dozing off then maybe don't worry too much, as long as you are aware that it can lead to some harder work later (but not impossible).
If you want to write out your day inEAS format I'd be happy to look at it for you.
