Baby weight


My DD's 14w6d and her weight's about 5.5kg. She was born 3.1kg and became 2.9kg in her first few days. I breastfeed her as per demand, no timing. Just as she wants. My breast doesn't feel full (actually feeling empty) but when I try to squeeze some milk, there's a pretty good amout coming out. What's your baby's weight during this age and is my baby doing fine?
