So just to mix it up, LO is now not waking at all today. Had good night with only one wake up and then woke at 7 am and has been fussy and so sleepy. Barely making A time of 1.5 h and this last A time barely woke up to even feed. Sleeping 1.5-1.75 hours naps. When I did wake her during A time, she cries and fusses! No fevers, eating ok, peeing ok, less poops! What do you think? Growth spurt?
