Per my kids as babies and my observations of them and their sleep/nap habits:
after about 1 hour, you say your baby "wakes." But looks clearly still tired.
My perspective is, she is NOT really waking up. Nor is awake fully. She is merely, stirring... many babies or adults for that matter.... sort of stir in their sleep or while sleeping. Intermittently. Which is normal.
BUT... if you then pick baby up and start talking to her and making her... awake.... BEFORE she needs to be awake or is ready to be awake... then yes, your baby will NOT be getting a full nap... AND will still be very tired and fussy. Because you woke her up.
So my tip is this: when/if she stirs sleepy-eyed after 1 hour... just let her be. Don't even let her see you... nor hear you. Just observe her. It may very well be, that she WILL go back to sleep.
This is what both my kids did, as babies. BUT if "I" then interrupted 'their' stirrings and sporadic wakings, then... they got fussy and still tired. Because it was actually "I" that woke them... before they needed to be.
My son in fact, from about 6 months old and even now... will stir or seem awake after about 1 hour of napping.... BUT that is how he is. He simply stirs and even eyes open... after 1 hour of napping. So I do NOT wake him. He will stir and look around, but he ALWAYS goes back to sleep... if I let him... be undisturbed in his manner of napping. I know this about him.
A few of my friends... had babies that they thought would not nap for any length of time. And while with them... I actually saw, that it was them themselves that was waking baby and not letting baby nap fully. Because.. at ANY stirring or noise or movement baby did... they would immediately pick baby up and "assume" their baby was done napping. I told them... NO... baby is not done napping. He/She is still napping... just let her be... just because a baby stirs/moves/makes noise in their sleep... it does NOT mean they 'woke up'. So don't wake them. Let them sleep... and after their stirring they may very well self-soothe and go back to sleep, if you do not interrupt that.
all the best,
Susan
