Yes it will pass.
At times of developmental changes & growth-spurts, it can tweak a child's sleep patterns. It passes.
No need to do major changes or a major renovation in everything or sleep times or nap times.
I don't know where she sleeps or if in a crib... but if she is waking and perfectly happy and content and babbling/laughing entertaining herself... there is no reason to go and pick her up or get her or to "stop" the moment. Just let her be. My son and my friend's baby... used to do that too. We were GLAD... because for me, my son could entertain himself and was perfectly happy... it was like his own time of discovering himself. When he got older, he'd actually tell me "me not ready yet" and he'd WANT to stay in his crib and hang-out and "play." THEN, when he did want to come out and for me to get him... he'd "tell" me.... calling me or then screaming (the kind for me to come and get him).
My son, at times, (and for my friend's baby), they could be having fun/entertaining themselves in their crib for even 1/2 to a full hour. Just happy as a clam. Or, sometimes my son would just fall back asleep ALL ON HIS own.
For my son, we had baby-safe stuffed animals in his crib... and he had his lovey- a stuffed cow. And he'd just be content and having fun in the crib. So... it was up to Me, to go by his cues... and "learn" that he was just fine being himself. And that, not every single waking or activity or noise in the crib that he was doing, warranted my to "interfere" in that process. I let him be.
So, sort of enjoy this time now. Your baby is being self-reliant and entertaining herself and is happy going about it, and discovering her voice and inflections. Its a good thing. Its NORMAL.
No need to stop or hinder things like this. Its purely developmental, and at each age/milestone change.
*I know I didn't answer your question exactly about her waking you all up at that hour/time of morning... what you may want to do, is just bring her into bed with you? But she may still just be awake and still making noise.
All the best,
Susan
