I used to work at a pharmacy (many moons ago...) and we would recommend Hamilton Toddler milk. It's got the highest UV rating (the actual figures can't be published above 30+) of all stocked by most pharmacies. It also has the least amount of potential irritants. I can't remember the exact UV blockage figure, I think it was in the region of 60. Most 30+ hover up to 45, not many are higher than that. I use this sunscreen on my DD who has extremely fair skin and she's never been sunburned.
