My mother in law had a poodle with kidney failure that had twice weekly dialysis treatments. She loved Missy so very much that she just could not let her go. Missy was in a lot of pain those last few years and towards the end started having severe seizures.
Your baby will tell you when it is time to let go. Listen with your brain and your heart.
I want to send you hugs
. I know you hurt beyond all hurting. Listen to your heart and to your precious little one. The time may be near that you will have to ease him over to those painfree, carefree green pastures at the edge of the Rainbow Bridge.
