Help won’t eat bottles!

Na

My daughter is 9 1/2 months and is starting to refuse her bottles. She normally does this when she’s teething but I still manage to get some in her. This time around she is just refusing. She will drink half her 8 oz bottles at max which she gets 4 of during the day. I know you aren’t supposed to give whole milk until a year old but I’m worried she isn’t getting enough. Maybe she’s ready for milk? I need help ladies!
