tsh levels during first 3 months of life
TSH Timeline in Early LifeFirst 30 minutes to 24 hours: A natural physiological surge happens due to delivery stress and cold air. TSH can spike up to 60–80 mIU/L.
Days 2 to 3: Levels drop rapidly to below 10 mIU/L.
1 week to 1 month: Levels typically settle into a normal range of roughly 1.7 to 9.1 mIU/L (varying by lab).
1 to 3 months (and beyond the neonatal period): Healthy serum levels generally drop below 6.0 mIU/L, aligning closer to standard pediatric baselines (roughly 0.5 to 7.0 mIU/L depending on the specific laboratory's assay

Greetings
clear downward trajectory in TSH is visible, decreasing steadily from 14.64 at 2 days old to 5.410 at 4 months and 9 days old.
The infant's most recent Free T4 level is recorded at 1.22, which pairs with the stabilizing TSH to suggest naturally resolving thyroid function.
Clinical details note the baby has achieved a healthy weight of 7.35 kg, receives a 50:50 mix of breast milk and formula, and exhibits no fever or vomiting.
The reported bowel movement frequency of once a week with a toothpaste consistency is a common, typically benign presentation for infants on mixed feeding regimens.
Because the TSH levels are naturally trending toward normal pediatric reference ranges without medication, continued routine monitoring is the standard next step.
