Does anyone know of any online resources for failure to thrive in infants?

Needs? There are many sites that have reliable information: mayoclinic.Com, hopkinschildrens.Org, healthychildren.Org, and kidshealth.Org. If your child has failure to thrive, a thorough history (illnesses, family history, food diary, etc) should be done with a complete physical and possibly labs and other testing. Many causes: poor nutrition, genetic / hormones, reflux, illness, heart/lung probs, etc.
