(((hugs))) honey, it's so hard to try to figure out what the "right" thing to do is. And even if you don't get it perfect (or anywhere near it for that matter) I'm sure your LO will be fine as she clearly has a mama that loves her!
FWIW, my dd2 would have nothing to do with solids until she was 8 months old, dd1 took to them straight away at 6, and ds has been kind of in between.
