I'm struggling to get my 18month to keep her hat on for more than 30 seconds. We're persisting but going to Spain on holiday next week. I wondered if there were any SPF sprays out there that I could use on her head without it looking like she's got a greasy comb-over! She is fair skinned with a reasonable amount of hair and obv we'll keep her out the sun esp during the hottest times as much as possible.
