We’ve had to have Ruby’s feet poked over and over and over. As in every couple of days. It’s been sad for her :(. We have to go in every week anyways to her normal pediatrician to get her oxygen saturation and weight checked. She isn’t gaining weight either. Her bilirubin count was going down and so we had a break from the pokes, but then the next appt they had gone back up quite a bit and so they had to order the lights for her to get her jaundice to go away. Which between the jaundice and her heart, there is our reason for why she is SO tired and why she isn’t gaining weight—because she’s so very tired all the time! 
So we get to use these for a week! And get her tested again at the end of that week. We are now tethered to the wall with her. We are supposed to have them on her for as LONG AS POSSIBLE each day. It might be a long week!
