I got a call last night from the mom of the blue baby. He had been taken off the vent at about 4 PM yesterday.
This morning, he was allowed to nurse, and he did latch on and nurse successfully. They are removing his arterial line today also. He maintained his blood gasses during the night.
They are hopeful to take him home in the next couple of days. This is an answer to prayer! I am so glad that this family will finally get to take their baby home.
