Almost 12 month old waking up at 2-3 am every night


My Almost 12 month old has been waking up between 2-3 this entire week, it takes her 2 hours to go back to sleep. She’s fed, eats great during the day, clean diaper, I’m not sure what’s going on. Her bedtime is around 7ish, wake windows are 3/3.75/4. Sometimes 3/4/4. She’s on two naps and is always so tired in the morning.
