Hey Carmen, sounds like you're beating yourself up a bit over this hun - shame there's no instruction manual.

Just wanted to add my experience. My bub refused food at all until she was well over 9months old. And then she was nearly 12 mnoths before she was having 'three meals' a day. They don't actually 'need' any solids until after 12 months - it's just an experience.

Maybe she just isn't ready if she's still gagging and unusually slow to take to it.
