Paisley isn’t doing well. I’ve had to do A LOT of talking this week. So clearly the last thing I wanted to do was talk about it even more with y’all. Her liver has a disease. causing her to have failure to thrive . We have absolutely no idea why her liver is doing this. We are in the process of figuring it out. Whatever it is, it’s extremely rare. We are doing test after test. Tomorrow we do another liver biopsy so hopefully that leads to some new answers. Please pray for us to find answers as to why this is happening so we can treat her properly & get our sweet girl on the road to recovery💗🙌🏼 This has been EXTREMELY difficult on myself, my husband & Aniyah. Thank you to everyone who’s reached out. Nobody wants to see someone they love more than anything in the world suffering. My heart is just breaking for my Sweet P. No baby should have to go through this. I’ve got to see who is truly there for myself, my husband and my children this week. Thank you, thank you, thank you to the people who’ve called willing to do anything to help during this time.
