Thank you for the question you have posed on this site.

My information about the levels of the thyroid hormones is as under:

At birth, babies have very high levels of TSH, which can go up to even 60-90 mIU/ml. The levels stay high, and the normal range on day 4 is between 0.4-16 (Hence, her level of 18 is borderline high).

The T3 and T4 levels on the 4th day in your baby seem to be within the normal range (T3 should be between 62–243 ng/dl and T4 between 8.0–20.0 mcg/dl on days 4-30 of life).

Looking at this, I would not recommend any treatment at present. You should repeat the tests after a month and see what the levels are.
