Sleep trouble all of a sudden! What the h@ll! Need Help and Advice please :)

Gianna has been sleeping through the night 9-10 hours since she was 2 months old, sleeping from 9-9:30pm to 7-8am.
The last 3 nights she has been waking at 5am, 5:30am, and last night 3am.

She is about 4 months old and hasn't awoken for a feeding in the middle of the night since she was about 4 weeks old.

I stopped Bf'ing totally as of a week and half ago, and she is on 100% formula taking in about 20-24 ounces a day. (PED said 20oz should be her min.)

I can't get her to eat more. This is out of the oridinary for her and I am worried something may be bothering her causing her wake up.

She has had teething symptoms since 2 months old, and her bottom gum, is really white, but i can't feel anything either.

Could she be teething? Hungry? Ear infection? I cannot go back to waking up in the middle night, my sanity depends on it, and I start work in 2 weeks!!

Help! ANy advice? Wisdom>

It's definitely teething. I'm sure by the weekend you'll see that tooth appear. Once it comes through, she'll go back to normal.

Peyton didn't want to eat, she'd push the bottle away, she would wake up.

It's totally normal.

Teeth oh boy.

She doesn't push the bottle away, but she has been eating less at a feeding and sleeping alot more. Is that more teething symptoms?

TIA

Most likely teething. They say it's the most painful before we see/feel any teeth.

My DD has been doing this too and she is about the same age.
