Insect Repellant for Infants

Hi all!  We are going to a very mosquito populated place this summer and I would love some recommendations for a good insect repellent for a baby that will be six months old. If my grandmother weren't in her 90s and dying to meet my daughter we wouldn't be going due to the insects alone. I've seen babyganics and honest company have products but not too many reviews.  Thanks in advance!
