Till 1-1 1/2 month of age eyes will be little bit yellow and skin colour will be mild yellowish.. nothing to worry about that..but if you have any doubt get TSB and Thyroid profile done..observe stool colour and urine colour..physical examination is needed..go and consult nearby Pediatrician

Give proper feeding

You have done blanch test and skin appears yellow it doesn't mean that your kid has jaundice. Only blood report is accurate do TSB

Mild jaundice can persist up to 2–3 weeks in many breastfed babies and weight gain here is reassuring. However, since jaundice is still visible at 21 days, it is better to repeat bilirubin testing (including direct/conjugated bilirubin) once and get examined by your pediatrician. Please seek earlier review if: • baby is feeding poorly • excessive sleepiness • fever • pale/white stools • dark urine • poor weight gain • increasing yellowness.
