Think I saw you say she's cutting 4 molars atm? Maybe offer foods that don't require much chewing/gumming for a couple of days. It's most likely the gums being really sore that's putting her off.

We don't do separate foods here either or force feed. Once older we do encourage a few more mouthfuls as we know we'll hear 'I'm hungry' shortly after lol.

I don't think it hurts to cater to sore gums tho. Soon she'll have 4 chewing teeth and will be back to eating all the harder foods again. But yeah, keep up the milk intake and add some softer foods and fruits for a bit would be my advice
