By the way , there is a Pediatric Endocrinology expert forum here, you can post your daughters values (TSH, free T3 and T4) and ask the doctor.

High TSH means hypothyroidism, but if it's slightly elevated that can happen in new borns, but you need to look very close to see if your daughter doesn't have congenital hypothyroidism. Yes, you should go to the Pediatiatric doctor and ask him he's opinion.
