I think Weight Gain Resistent is a better term. Every time I hear syndrome it stresses me out big time. Now I am hearing failure to thrive, I already feel bad enough seeing V so small and taking forever to gain weight. I feel as tho I am being looked upon as being a bad mum. It amazes me to think that my little V can lose 10% of her body weight in a week from being sick, which would normally take her 6weeks to gain.
So seeing Failure to Thrive really makes you feel more like you are failing your bub.
