For a complete evaluation you should take her to a pediatric ophthalmologist...
Do you know what level she can see (20/20, 20/40, 20/60 etc) now in her "lazy" eye with her best eyeglasses in place?
The vision should not get worse, but it will not get better then she has right now with her best glasses
in place. She should be able to see well enough for all her life activities.....although 3D movies probably won't work for her :( (the explanation is kinda complex...)
I am sure that it has nothing to do with your pregnancy. It just happens.
Let me know if I can do anything else to help.
