How to Bathe Your 7–9-Month-Old Safely

The short answer

At seven to nine months your baby may try sitting, reaching and moving towards an interesting object. Splashing and grabbing toys are natural, but sitting on a dry floor does not mean sitting unaided in slippery bathwater is safe. A bath is not a balance test. Continue supporting a baby who cannot sit independently. Even one who can sit may lean forwards or sideways without warning, so adapt your hold to the bath and their movements.

Keep in mind

At seven to nine months your baby may try sitting, reaching and moving towards an interesting object. Splashing and grabbing toys are natural, but sitting on a dry floor does not mean sitting unaided in slippery bathwater is safe.
Water should be comfortably warm, not hot. Run cold water first, add hot water, mix thoroughly and test at different points with your wrist or elbow. A thermometer is helpful but is not a guarantee.
Lower your baby gently, support them and keep their head above water. Clean the face using small amounts rather than pouring water into the nose or mouth. Adjust your hold as skin gets slippery.
If your baby is unresponsive, not breathing normally or struggling severely to breathe after being underwater, call 999 immediately. Remove them from the water if safe and follow the call handler's instructions. This is not a substitute for first-aid training.

Bathing a baby who is learning to sit

A bath is not a balance test. Continue supporting a baby who cannot sit independently. Even one who can sit may lean forwards or sideways without warning, so adapt your hold to the bath and their movements.

Why close supervision is essential

An adult should stay within arm's reach and ready to hold the baby immediately. The AAP calls this touch supervision. Even shallow water is dangerous; drowning can happen quickly and quietly.

Do not leave your baby in the bath to answer the door, check your phone or fetch a towel. If you must leave, take them out, wrap them up and bring them with you. An older sibling is not a replacement for adult supervision.

Getting ready before bath time

Set out a towel, clean nappy, clothes and mild cleanser within reach. Keep the bathroom comfortable and prepare, mix and check the water before undressing your baby.

Avoid needing to reach for shampoo while holding a slippery baby. Silence the phone and agree who is responsible for supervision. Empty the bath straight afterwards.

Checking the water temperature

Water should be comfortably warm, not hot. Run cold water first, add hot water, mix thoroughly and test at different points with your wrist or elbow. A thermometer is helpful but is not a guarantee.

Never add hot water while your baby is in the bath. The AAP's suggested 49°C limit concerns the hottest water delivered from the tap to prevent scalding; it is not a recommended bathing temperature.

Bath seats and non-slip products

Baby bath seats can tip or allow a baby to slip free. The NHS and AAP warn that they cannot replace an adult who remains immediately beside the baby.

Nonslip mats may give a firmer surface but cannot prevent a baby leaning into the water. Check sharp tap edges and wet floors; have a secure grip for lifting in and out.

Keeping your baby comfortable

Lower your baby gently, support them and keep their head above water. Clean the face using small amounts rather than pouring water into the nose or mouth. Adjust your hold as skin gets slippery.

A little splashing, listening to your voice or playing with a toy may make bath time pleasant. There is no need to make it long. Finish if your baby becomes cold, tired or unsettled, and dry skin folds gently.

Electricity, taps and bathroom access

Keep hairdryers, phone chargers and other electrical items away from the bath. Never use electric appliances near splashing water. Put cleaners, medicines and small lids out of reach.

Drain the bath, buckets and bowls after use. Keep the toilet lid shut and, if possible, secured, and prevent your increasingly mobile baby entering the bathroom alone.

What can you do today?

Before the bath, take a couple of minutes to collect everything, check the mixed water, inspect the floor and decide who is supervising. Complete this preparation before placing a baby in water.

Watch what your baby likes to reach for. If a toy or tap encourages sudden leaning, move it or reposition your baby. Bath time can be both enjoyable and safe.

When to seek emergency help

If your baby is unresponsive, not breathing normally or struggling severely to breathe after being underwater, call 999 immediately. Remove them from the water if safe and follow the call handler's instructions. This is not a substitute for first-aid training.

Persistent coughing, abnormal breathing, unusual sleepiness or behaviour following a water incident requires prompt assessment. Seek medical attention for scalds in infants; do not dismiss a serious incident because they seem better briefly.

When to seek support
