During the day time use langot n while sleeping u can use diaper. I do that since my baby was 2 months old bcoz due to wetting the langot n then changing it he would not sleep well. N while making him wear diaper I make sure to apply sebmed diaper rash cream. This way his sleep.is not disturbed n during day he is diaper free. So till now he hasn't got any rash

I will advise you to not to use diapers in summers also you not mentioned age of your baby if your baby is less than 6 months old let him poo and use cotton pothis of cotton diapers that are available
