Can anyone recommend a foot deodorant for babies (if it exists, safe to use)?

It is not recommended to apply deodorant for babies due to their extremely sensitive skin. It is better to bathe your baby if you notice a foul smell. Due to the warm and humid weather in Singapore, it is good to bathe your baby a few times a day. I bathe my baby twice a day, once in the morning and once at night. You could add in an afternoon bath if the odour is too strong. The smell could be due to food which is not processed correctly by their body. Try keeping your baby's body dry as much as possible and apply talc free lotion powder to keep your baby feeling fresh and comfortable. http://canigivemybaby.com/deodorant/
