Congratulations to both of you!! You have a fighter...good for her. My sister was 2 1/2 lbs at birth, she is 51 years old now. She was a fighter at birth and still is to this day. It's just part of her make up and personality.
Glad to hear Izzy is resting well, that way her body can continue to grow and get stronger.
Wishing you all the best!! Take care!
