Question
At 8 months and 27 days old, my baby has a bone density that is more than one standard deviation below average. The baby is 69 cm tall, weighs 8.2 kg, and has a head circumference of 42.5 cm. Is this a sign of developmental issues? Will the baby be too thin?
Answer
Based on the medical description, the 8-month-old and 27-day-old baby stands at 69 cm tall, weighs 8.2 kg, and has a head circumference of 42.5 cm. For a baby of nine months, the standard height is about 72 cm, weight is about 8.9 kg, and the head circumference range is between 42 to 47 cm. Your baby is not underdeveloped; they are just slightly thin, so there is no need to worry. For the low bone density, you can give your baby Longmu Strong Bone Powder or Children’s Diquang Calcium Powder to supplement calcium and ensure they get plenty of sunlight exposure.
