Is it good for a girl to wash her bottom every day?
The buttocks refer to the gluteal area. Generally speaking, it's better to wash a baby girl's buttocks daily. However, if the baby has sensitive skin, daily washing may not be recommended. The analysis is as follows:

Baby girls have delicate and sensitive skin. The buttocks area is in prolonged contact with diapers or disposable training pants, making it prone to accumulation of urine, fecal residue, and bacteria, thereby increasing the risk of skin problems such as diaper rash and eczema. Daily cleaning of the buttocks helps remove these contaminants, reduces bacterial growth, keeps the skin clean and dry, and prevents skin inflammation and infections. It is recommended to use lukewarm water and non-irritating infant-specific cleansers, gently wash and thoroughly rinse, then pat dry gently with a soft towel, ensuring the skin is completely dry. This helps maintain the baby girl's personal hygiene and supports healthy development.
Although daily washing of a baby girl's buttocks is beneficial, appropriate caution is needed under certain circumstances. In cold winter weather, washing frequency can be reduced as appropriate to prevent the baby from catching a chill due to frequent washing. Additionally, if the baby has particularly sensitive skin, proper techniques and moderate washing frequency should be used to avoid adverse effects caused by over-cleaning.
