Thank you for the well wishes, I hope and wish you and your baby the best too.
All this testing is all a loooong process, hopefully the MRI will give you a definite answer of what it is. I would say dont worry about the leaning to the side just becuase every baby is diferent, but you are her mommy and mommy's know best, so if you think something is wrong, mention it to the doctors (I would).
Good Luck with the eye exam! and let us know the results!
