My son from last two weeks start developing itchy rashes like swollen bump on his buttock face r some times on his arms.. after some it shrinks to very small size like mosquito bitten mark.. also i would like to inform he eats lollipops and candies previously twice or thrice a day but that habit of him also now came down like now he is eating once in two days .. yesterday he ate , today i notice one bump like itchy rashes on his buttock and one on his arm.. please suggest me how can i get rid of this thing as he is a small kid its getting difficult for me to make him completely avoid candies or toffies.. is that means he cannot have sweet throughout his life ? Please help
