Looks like Taylor's blood vessels had built up quite strong muscles to pump all of that of blood due to her heart defect. Now that it's repaired and not pumping as much, the vessels are too strong. This was why she seemed to be having more trouble. Thankfully, they are able to help her with that with some medicine for awhile. This will help her vessels relax while it remodels itself to it's new system.
Tay is great otherwise today, spite the fact that she could not eat. She was awake for long periods of time throughout the day, just hangin and looking around. Here's some cuteness for you..
