The child can use the baby changing mat throughout infancy, usually from birth until the age of two or three years and no longer wets the bed. Your child can use the bamboo fiber changing pad from birth, and when the child is two or three years old and no longer wets the bed, it can be stopped. The baby changing mat is generally spread under the baby, and when it is cold, you can add a layer of comfortable thick sheets, and when it is hot, you can replace it with a thinner sheet. If your child is wet, you can remove the diaper directly, and if the waterproof changing pad is wet, you can change it and wash it and put on a new one.
