couldnt you just offer a few finger foods off of your plate to play with and see if she tries to eat them? That way you are not making anything special for her but she gets to practice/learn about solid foods.
I would go the BLW route as Seona suggests and let her get there in her own time. Don't worry I'm sure she will be fine even if she does not take to it straight away. Food is for fun until they're one. (Doubling birth weight is not regarded as a weaning sign now BTW)
