You didn't mention WHY you wanted her to be eating solids. "Back in the day" we were told to add solids when an 8 oz. night bottle wouldn't hold them until dawn. If you are happy with the number of hours she's sleeping at night (it will be different for each baby)and she's doing well enough with her bottles during the day, don't worry about it. When I started feeding mine, I put them in a bouncy seat so that I'd have both hands free. Their instinct is to put their hands to their mouths when you put something new in it and of course from there they go straight for their hair! It's helpful to have a free hand to keep their hands cleaner. : ) Please DO follow the age-based dietary rules about wheat, citrus, dairy products and adding new foods one at a time that your pediatrician gave you. Life is complex enough later on without adding food allergies to the mix.
At your next doctor visit, ask them when they want HER on solids, not when a book says it's time. And with most things in life, if in doubt, don't. Oh, and I'm with you on eating solids with a spoon, not drinking them. I only put water, formula or breast milk in bottles, and juices when they were very small. As soon as they could drink from a tippy cup without choking, water,juice and later, milk,went only in the cup. I think it made it easier to wean them at 1 year since by then they were accustomed to drinking most things from their cup. The bottles only took a couple days to stop.
Hang in there. You'll do fine! Good luck with your bundle of joy!
