5 month old teething baby... No appetite.

I don't know if it's a growth spurt or her teething but she has no appetite...for a bottle...she will scarf down some baby food but is putting up such a fight with the bottle. Today she has only had 14 ounces so far and ate food three times (she eats half a big jar in one sitting) she usually eats 24-30 oz plus food 3 times a day. She's still peeing and pooping normally so she's getting enough I guess. She's happy and healthy. I'm just a worry wart. anyone else going through this?
