Brief Answer:
Kid is suffering from Subclinical hypothyroidism.

Detailed Answer:
Hello XXXX
Thanks for writing back

Kid is suffering from a condition called as Subclinical hypothyroidism(SCH).

Subclinical hypothyroidism(SCH) is characterized by a normal total or free T4 level and a mildly elevated TSH (typically 5–10 µlU/ml).
It is common in children.
Several recent pediatric studies indicate that progression of SCH to overt hypothyroidism (OH) is uncommon and that over a period of several years, elevated TSH usually either normalizes or persists but does not increase.

Since few cases of pediatric Subclinical hypothyroidism progress to overt hypothyroidism,its treatment can be deferred and periodic follow-up testing is the preferred strategy.

In my opinion,your kid only require regular follow up tests and there is no need of medicines at present.

If TSH > 20 µlU/ml then patient require immediate medications.

Developmental milestones of your kid is absolutely normal and there is no need to worry.

Get well soon.
Hope i have answered your query.
