Refusing milk after starting solids

Hello mummies, any of your babies start to refuse milk after starting solids? My 7.5mo baby just fights to drink milk and doesn’t seem to cry for milk as much anymore. She can be without milk for 8 hours?! I try to feed her worrying that she’s not drinking enough nutrients but it’s so hard when she keeps struggling and crying. I am mostly dreamfeeding her to top up. Feeling so lost 😭 Is this common? Is it a concern? What should I do?
