Worried about bug bites!

Jessica

We went camping last weekend and had a wonderful time but the mosquitoes were horrendous! Despite all our efforts (netting, layers, baby bug spray, citronella, smoky fire, etc.) my daughter (10 months) got bit as bad as us. Fast forward almost a week and the redness is getting worse. We are going to head to the doctor to be safe but what do you guys think, have you seen bites like these on a baby before? Is she just allergic?

We also went in the lake for a short time, could it be blue/green algae?

Thanks for your help!
