Can we freeze our baby's solids in advance? Are there certain foods that we should not freeze and must be kept & given fresh?

Yes, of course we can freeze solids. My 6months old son is under my mum's care while I am at work, and because he is hyperactive plus my mum has a bad leg, I tend to prepare and freeze solids so it's easier for her to prepare his meals. You can keep frozen solids for long periods, although I only store enough for the week (I prep every Sunday night). You can freeze also any kind of fruits/vegetables. However for avocadoes & bananas, preparing then fresh would be best. Also, it's an important note not to refreeze anything that has been taken out to thaw.
