Hi- well, how are things going this weekend? Still early waking? Sounds like you've got a happy LO- nice that she'll play in the crib till you get her!
You could try moving her bedtime back 30 mins and see if it extends her AM wake time. SOunds like she's getting plenty of daytime sleep. And, yes, 2-1 nap switch is around the corner and may be contributing, but it does seem early.
Also, just recovering from illness can throw sleep off..
Hugs and keep us posted!
