You are asking question regarding to development but you did not mention age/ birth history of child which is important t0 answer your question.
Don`t panic. Calm down, be courageous and get her treated.
Normally child walk alone by 15 month
Usual time of eruption of deciduous teeth- 6 to 8 month
If your child does not walk alone by 18 month.
I would advice:
You should get her evaluated once for her complaint to get her examined physically by a pediatrician
Wait and watch
Wishing your Child milestone speedy recovery.
