i'm sure you know that solids shouldn't replace milk, so as long as she is drinking plenty of milk i would say just let her eat! you might consider limiting solids to just once a day to make sure she is getting plenty of milk.
My LO was like that too when he started solids at 5.5 mos - I almost considered 'de-weaning' him but then he caught a bad cold and started teething, and flat out refused solids for about 2.5 weeks. we've just slowly started getting into it again. he'll eat a jar of baby food at dinner but often refuses solids at breakfast/lunch. i guess what i'm trying to say is - milk should be primary diet, and don't be surprised if the LO regresses a little bit with solids, and after that, just let her eat if she's happy to do so!
