As your baby grows, their diapering needs will change. Here are some key points to keep in mind: 1. **Diaper Fit**: Ensure the diaper fits well. Check the weight range on the package rather than the age range. If the diaper leaves red marks or leaks, it might be time to move up a size. 2. **Cost Efficiency**: Smaller diapers come in larger quantities per package, which can be more cost-effective. 3. **Signs of Readiness for Pull-Ups**: As your child approaches two years old, they might show signs of readiness for potty training, such as telling you when they need to go or tugging at their diaper. 4. **Changing Method**: Older babies might squirm more during changes. Consider changing them on the floor for safety. 5. **Diaper Rash**: Keep your baby clean and dry to prevent diaper rash. Use barrier ointments like petroleum jelly or zinc oxide cream if a rash develops.
