Sleep regression

Nikole
I'm pretty sure my 20 week old is going through a sleep regression. She has short naps, fights to go to sleep at 8 and cries and keeps dropping her pacifier. Then used to sleep till 6 am or 7am and now wakes between 4am and 5 am. Is this sound about right? Will she correct it or do I need to do something? I'm exausted! She moves so much in her crib all night. Qq
