S.,
My son had this (basically I believe she swallowed fluid when she was born) which is why they kept her overnight. I think they pumped my son's stomach or suctioned it out of him. If she still had a lot of fluid in her and only lost 1.7 ounces I'm guessing she went home with the fluid. I would call your pediatrician and see what he says, perhaps they will want to examine her sooner. I believe it is fairly normal. and the pink stuff- well its just your hormones left over in her and should go away in a couple days. I'm so pleased for you that she is nursing well and if she is peeing and pooping well already then you guys are off to a wonderful start!
Congratulations on your new baby girl! :)
