Baby not gaining weight

Samantha • Mommy to Alyson Rain 💓

My baby has been in the nicu for a week now because of her sugar levels were to high but now there low and stable so I thought they were going to discharge her but now they want her to get back to her birth weight she was born 5lbs 7oz and no she’s 5lbs 1oz every time she eats she poops like 2 or 3 times I don’t know if it’s the milk they are giving her or what I’m just hurting bc I want her home already. Any tips that can help ?
