any brand of mosquito repellent tats effective for toddler? how to stop itch after bitten?? Help!!

This is good, very effective and long lasting. But also a bit expensive too. Lemon is good for anti-itch. Can apply a bit of lemon juice over the itch area to stop e itch. Or wash with salt water for bites. If not dab with baking soda. VCO is also good got eczema or itchness from the bites too.
