The baby’s hand barbs may be caused by the baby’s love of eating his hands, the usual bad habits, or the lack of nutrition. Since babies often eat their hands, the skin of their fingers is soaked in saliva for a long time, so the skin around the finger nails is damaged, thus causing barbs. Bad habits, such as playing with water and toys, do not dry in time after playing and are not well protected, so they make them grow barbs. It is recommended that after washing your baby’s hands, you can properly apply hand cream to your baby, especially when the weather is dry. In the baby’s hands with barbs, there may be a lack of nutrition or vitamins, how to determine, you can go to the hospital dermatology or consult a doctor, parents remember not to give the baby indiscriminate nutrition and vitamins, etc..
