2. **Test with Your Elbow**: This is an old but reliable method. Run your elbow through the water. If it feels warm but not hot, it's likely in the safe range.

Gradually Introducing Your Baby to the Bath

When you've checked and adjusted the water temperature, gently lower your baby into the bath. Support their head and neck at all times.

If your baby seems uncomfortable or starts to shiver, the water might be too cold. If they look flushed or start sweating, the water might be too hot.

Monitoring Your Baby During Bath Time

Always stay with your baby during bath time. Never leave them unattended, not even for a moment.

Keep an eye on their body language. If they start to shiver, cry, or seem distressed, it might be a sign that the water is too hot or cold.

Bath time should be a relaxing and enjoyable experience for both you and your baby. By understanding and maintaining the right bath water temperature, you can ensure that it is.
