The short answer
For a baby aged seven to nine months, protection starts with reducing direct sunlight. Seek shade, choose breathable clothes that cover the skin, and use a broad-brimmed hat shading the face, ears and neck. Sunscreen is an extra layer, not a reason to stay outside longer. Even a brief pushchair walk needs planning around the season, UV level and weather. A shaded path through the park can matter more than simply increasing the SPF.

Keep in mind
- For a baby aged seven to nine months, protection starts with reducing direct sunlight. Seek shade, choose breathable clothes that cover the skin, and use a broad-brimmed hat shading the face, ears and neck. Sunscreen is an extra layer, not a reason to stay outside longer.
- For babies over six months, a broad-spectrum sunscreen covering UVA and UVB can be used on exposed skin; SPF 30 or above is a sensible choice. Check the product label and local guidance.
- Sunburn results from UV exposure, whereas overheating and dehydration are linked to high temperatures. Cloudy days still allow UV through, and shade is not necessarily cool.
- UV can reach the skin through clouds. Do not deliberately expose your baby to potentially harmful sun to provide vitamin D; discuss vitamin D drops with your health visitor or GP.
Sun protection is not just sunscreen
For a baby aged seven to nine months, protection starts with reducing direct sunlight. Seek shade, choose breathable clothes that cover the skin, and use a broad-brimmed hat shading the face, ears and neck. Sunscreen is an extra layer, not a reason to stay outside longer.
Even a brief pushchair walk needs planning around the season, UV level and weather. A shaded path through the park can matter more than simply increasing the SPF.
When should you go outdoors?
Reduce direct sunlight when it is strongest, often around 10am to 4pm. Treat this as guidance rather than a strict timetable and pay attention to local UV levels and temperature.
A tree, parasol or pushchair hood may help, but sand, water and light surfaces reflect UV. Never drape a thick blanket over the pushchair and block ventilation; the temperature inside can rise.
Choosing clothing and hats
Light, loose clothing made from closely woven fabric helps cover the skin. A wide-brimmed hat should shade the face, ears and nape without obstructing vision or fitting unsafely.
If your baby removes their hat, look for more shade rather than making it a battle. Long sleeves alone do not guarantee good protection if the fabric lets a lot of sunlight through.
Sunscreen for seven- to nine-month-olds
For babies over six months, a broad-spectrum sunscreen covering UVA and UVB can be used on exposed skin; SPF 30 or above is a sensible choice. Check the product label and local guidance.
A mineral sunscreen containing zinc oxide or titanium dioxide may suit sensitive skin. A fragrance-free cream or lotion is easier to apply carefully than a spray near a baby's face. Check the age guidance, expiry date and instructions.
Applying and reapplying sunscreen
Apply as directed, typically about 15–30 minutes before going outdoors. Cover exposed areas including ears, neck, hands and feet, without letting the product enter the eyes.
Reapply approximately every two hours and after swimming, sweating heavily or towelling dry, unless the label says otherwise. Water resistance is not waterproof protection.
Sunburn versus overheating
Sunburn results from UV exposure, whereas overheating and dehydration are linked to high temperatures. Cloudy days still allow UV through, and shade is not necessarily cool.
On a hot day, unusual irritability, reduced feeding or markedly fewer wet nappies deserve attention. Move somewhere cooler, offer regular milk feeds and observe your baby. Do not replace breast milk or formula with water; small sips with solids may be suitable after six months.
What can you do today?
Before leaving, choose a cooler time and shady route, prepare light clothing and a hat, and use suitable sunscreen on uncovered skin. Take feeding supplies and a spare change of clothes.
At the park, notice whether your baby seems comfortable as well as how long you have been outside. Move as the shade moves and reapply sunscreen when needed.
When to seek medical advice
If painful redness or blisters develop, move out of the sun and seek medical advice. Do not burst blisters or use improvised treatments. Extensive burns, fever, significant pain or an unwell baby need prompt assessment.
Seek emergency help for difficulty waking, reduced responsiveness, unusual breathing or severe illness in the heat. Persistent vomiting, inability to feed and very few wet nappies also need urgent assessment.
Two common questions
UV can reach the skin through clouds. Do not deliberately expose your baby to potentially harmful sun to provide vitamin D; discuss vitamin D drops with your health visitor or GP.
If sunscreen causes a rash or redness, stop that product and ask a health professional for advice. You can continue using shade and protective clothing.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
