Does this baby need medicine for hypothyroidism?

My friend in China has a baby having slightly high TSH, she is getting different opinions from different doctors there.  So she was asking me to post the question in this forum to see what doctors in U.S. will do for her baby.  Here are the test results, and the baby is about 3-and-half-moth old now.

(1) Test results when the baby is 7 weeks old.
Anti-TPO: 8.0 IU/mL (ref range: 0-12.0)
Anti-TG: 11.6 IU/mL (ref range: 0-34.0)
Total T3: 1.13 ug/L (ref range: 0.79-1.49)
Total T4: 78.3 ug/L (ref range: 45.0-120.0)
TSH: 6.96 mIU/L (ref range: 0.47-4.64 adult)
Free T3: 4.05 pmol/L (ref range: 2.22-5.34)
Free T4: 14.96 pmol/L (ref range: 9.13-23.8)

(2) Test results when the baby is 11 weeks old.
Total T3: 2.3 nmol/L (ref range: 1.2-3.4)
Total T4: 114.0 nmol/L (ref range: 54-174)
TSH: 6.46 mIU/L (ref range: 0.34-5.60)
Free T3: 7.0 pmol/L (ref range: 3.54-10.16)
Free T4: 19.4 pmol/L (ref range: 10.0-31.0)
Anti-TPO: 20.0 IU/mL (ref range: <35)
Anti-TG: <20.0 IU/mL (ref range: <40)

(3) Test results when the baby is 13 weeks old.
Total T3: 2.9 nmol/L (ref range: 1.2-3.4)
Total T4: 157.0 nmol/L (ref range: 54-174)
TSH: 6.694 mIU/L (ref range: 0.34-5.60)

We can see the baby's TSH is 6.XX and higher than the ref, but the T3 and T4 are normal.  Does this normal for babies? and does the baby need any medical treatment?  Please advise.

This would be a good question for Dr Lupo in the related expert forum. If you look at the rt hand side underneath where it says community members, you will find the expert forum and just hit on thyroid.
Also, the total tests are outdated. They should be running free t4 and free t3 with the tsh.
They might need to look at the pituitary, with the tsh being off...but it is best to ask a doctor. Good luck! I hope everything works out well.

There is a pediatric endocrinology expert forum, try to ask the Dr. there, she's very good. As I know babies have a TSH higher then adults (what is the normal reference??' I don't know), you need to watch it very close because it's important for the development of the baby.
