M.K.
I don't understand why your doctor would be concerned. My DD didn't eat solids until she was about 12-13 months. She did the same thing with chunckier foods like gagging and throwing up so I stopped giving them to her and only offered them about once a week. They mostly just sat on her tray but eventually she tried them on her own and now she's 16mo and eats anything I put in front of her. It took her a while to figure out that she had to chew them before swallowing. I personally wouldn't be too concerned it just sounds like she's not ready for solids yet.
As for the no crawling, do you give her plenty of tummy time? I know once they figure out how to roll over they just do that every time they go on their tummy. My DD did the same thing she's now a speed demon and my nephew never crawled he scooted everywhere and then went straight to walking. Hope this helps and shows that its ok for kids not to do exactly what everyone else's kids are doing.
