My daughter will be 2 years old in late March 2017 and was diagnosed with arthritis. So far it's been her ankle knee and finger. Cancer runs rampid in her father's and my family. Not sure what to ask. My sister died at 9 from leukemia. Anyone have any info on anything about children using this med that they know of? Any advice tips or anything to make her more comfortable since she can't talk yet? Maybe something that would make you feel better? Any info is appreciated greatly.
