Sleep regression or teething?

Rebecca

My 9 month old daughter has been only having short naps during the day or skipping naps. She’s been having a short nap in the evening (I’ve been hoping for her to be out for the night) and staying awake until 11pm- midnight. Then sleeping until about 10am. She used to be on a great schedule of bed by 9pm and wake around 8am.

Is this a sleep regression or teething causing this?

Any advice would be greatly appreciated.
