Despite having harsh winters and cooler temperature, the sun here in northern Europe can be pretty harsh in the summer, especially those who live further north and experience 24 hour sunlight.
My friends recommend the Alba Botanica, Natural Very Emollient Sunscreen, Kids, SPF 45. It's always best to get SPF 30 above and this sunscreen for kids come in both 30 and 45. You can get it at iherb which ships to Philippines; it retails at about PHP 433.

However, according to the product information, it's for babies aged 6 months and above. How old is your baby? For younger babies, best to check with your doctor which ones to use.
In general try to look for non-fragrance and oil-free in case of skin sensitivities.
