How soon you can change the diaper after breastfeeding depends on the child’s specific situation. If the child has sensitive skin and often has diaper rash, the diaper needs to be changed promptly; if the child often spits up, it can be changed after 15-20 minutes. 1. Sensitive skin: Some children’s skin is particularly sensitive, especially to secretions such as feces and urine. If you don’t change it for a long time, it is very easy to develop diaper rash, resulting in redness and erosion of the buttocks. Some may even induce serious problems such as perianal abscesses. At this time, regardless of whether they are breastfed or not, they should be changed in a timely manner. 2. Children with frequent milk overflow: in this case, after eating milk, it is best not to change the diaper immediately, resulting in the child’s milk overflow aggravation, choking and coughing in severe cases. You can change it after 15-20 minutes.
