Baby teething not wanting milk

My lo today ate horribly only like 3 oz at most and her last feeding she didn't want to eat at all. I offered squash and she ate the whole thing but still no milk. I don't want to send jer to bed like that but she just won't drink her milk. She's 5 mo and her gums are b hurting her so had. What would u all do keep trying the bottle before bed or just let her b since she so tired?
