This is the one product I have consistently used on my son. We have had him out camping since he was 4 months old, and most natural alternatives just weren't effective. At about a year old, I started using this on him. This is what we keep around, and I even use it myself. He is 4yo now, but I still make sure this is with us so he doesn't use my hubby's bug repellants, that often have very high deet levels.
