Help and exhausted mama out!

Girls, what is happening?!

My daughter is almost 7 months. She used to sleep 7pm-7am without waking up at all. She slept like this for 2 months straight.

As soon as she turned 6 months, she started waking up through the night and seems hungry! Yes she is teething, she got 2 bottom teeth the past couple of weeks, but still after they cut, she continues to wake. I tried not feeding her so we don’t create a habit of waking up to feed, but she does seem hungry so I end up feeding her every night. She now wakes up at least twice throughout the night 😩

Is there another regression? What can I do to get her to go back to normal sleeping hours?
