When a mom has chickenpox, her child may be infected if she has breastfed. Chickenpox is an acute, highly contagious disease caused by human infection with the chickenpox virus, which is transmitted mainly through respiratory droplets or direct contact. It is not recommended to breastfeed the child if the mother has chickenpox. Chickenpox is contagious and can be spread through droplets and direct contact. Close contact with the child during feeding may spread chickenpox to the child. Adults with severe chickenpox symptoms need medication, such as vasiclovir hydrochloride tablets and acyclovir dispersible tablets. However, the medication taken will have a certain effect on the child, and most of the medication may be metabolized through breast milk, so it is better to need to recover from the condition before feeding. If the mother has chickenpox, it is recommended to seek medical treatment promptly. When using medication, you should follow your doctor’s advice and not use the medication at your own discretion to avoid adverse consequences.
