"Are bumps and dry mouth common in a 1-year-old baby?"

Dry patches and a dry mouth in a 1-year-old baby are common issues. The main cause is often their saliva. The best treatment is to hydrate the skin with a fragrance-free moisturizer like Base Glaxal, Cerave, or Aveeno. This can help reduce irritation and dryness. These creams can be applied as often as needed and are not harmful if a small amount is ingested.
