Worried about weight loss
My daughter was recently born at 30w6d due to preeclampsia and fetal distress. Once born it was discovered she had IUGR as well and was born weighing only 1,066 grams. Otherwise she's doing well with CPAP on room air, tolerating feeds well so far and has a line in her umbilical. She's had a few low blood sugars and mildly elevated bilirubin and they have her under a light and she's already doing better. However she has been losing weight.
It's only been 72 hours since her birth and she's already lost 10% of her birth weight, down to 960 grams. They're going to start fortifying her breast milk tomorrow and she has been tolerating feeds well. I know it's normal for her to lose weight in the first few days and the NICU team doesn't seem concerned yet but she's just so TINY, and it has me worried that she's just never going to gain weight and she's just going to waste away.
When should I be worried about her weight? I know there are lots of success stories for babies like mine and I know we're incredibly lucky for her to be doing as well as she is otherwise, but has anyone experienced their IUGR baby fail to gain weight?
