For how many months I can use extra small sized diapers for my baby boy

A. Make him wear according to his weight. Diapers can be used for babies during day and night. But take few precautions to avoid rashes or infection. First of all, maintain good hygiene by cleaning the area properly with soft cotton wool dipped on water instead of wipes, change the diaper after four to five hours or when soiled by potty immediately, never wear diaper on wet bottom, let the skin dry first and then Apply cream like Vaseline before wearing diaper, if rash is there then appky ezinapi cream and let the rash heal. Give diaper free time intermittently for one or two hours
