Hi Mackie and Welcome to HealingWell!
The baby's plight and yours just touched my heart. I would think that since the baby's heart has been surgically fixed, that this probably is not the problem. Please ask his Dr. re this.
However, not knowing what the little one's background is could play a part in all of this. Being a Foster Parent, you should be aware of the baby's past history?
The Failure To Thrive (FTT), can be brought on by so many things, including his possible CF diagnosis.
Here is a link to a site that should help to explain more.
My thoughts and best wishes to you and your little one.
Hugs, Teri :)
