Question

Accepted Answer

you can choose according to the weight and size of the child
No problem in making the child wear diaper through out the day.
Important is to change it regularly when it becomes full. Now there are diapers with extra absorption capacity due to high crisscross sheets and child remains dry for more longer duration. Urine is absorbed faster and contact time of skin with urine is negligible.
Limb bend and kidney or  problems due to diaper is myth.

Accepted Answer

Diaper should be used in baby with all precautions specially in mansoon season as the skin is highly sensitive to infection & allergy . 
A deliberate use of mousturisation with a good lubricant or a petrolium jelly is important.
Frequently checking the diaper and changing is required as it will reduce the chances of infection and friction over skin leading to rashes. 
Tight gucloths and unnecessary layer of cloths can be a cause of diaper rash which should be avoided. Use cotton clothes . humidity should be avoided 
Diaper free interval for at least 2-3 hrs in a day is important too .
