Not looking to debate, but from everything I've read, bug spray is not harmful to baby. If you're concerned about deet though, you could use Skin So Soft. I also used one of those little personal bug repelling fans that off makes when DS was an infant. They work moderately well.
I used skin so soft during my first pregnancy, but if I was visiting an area with mosquito diseases, I'd go for the DEET. The diseases would be more harmful to baby than the DEET.
I use an organic, all natural insect repellent lotion.i buy it from a local store, but if you look locally at a natural store im sure they would have it. The skin absorbs everything, and also you would be inhailing the toxins everytime you spray it..for me, if its a product i wouldnt drink, i dont put it on my skin either.
