Hi,
Thanks for the query.
It is not true that eating hot foods will affect the hair of the baby.
Pattern of baby hair will be decided by genetics and nutrition.
As your husband is having bald head, that may affect the baby after he becomes adult.
Sometimes may not affect also. That can not be decided now.
Take nutritious diet containing cereals, dhal, fruits, vegetables, milk, egg, meat, fish etc.
Adequate nutrition is important for normal growth of the baby.
Better to avoid too hot foods.
Regular antenatal checkups and
ultrasound examinations are needed to monitor the growth of the baby.
Continue the medicines prescribed by your doctor.
Take care.
