Baby refused morning bottle.

Okay so it's 725 am and my daughter woke up at her usual time at 615 and didn't want her bottle, she either kept chewing on the nipple or just pushed it away. This is very unlike her, usually she'll drink it and go right back to sleep. She's also been a little extra fussy this morning. She's had a minor cold the last few days (just a slight change in temperature and a runny nose) but she's also been teething as well (the top 2) Anyway, she drank maybe half an oz and I had to throw the rest away.

Do you think it could because she's teething that she doesn't want the bottle? Any insight would be wonderful. Thank you!
