I wonder if these are not too large doses for such a small child.

Good morning. My child is 5 years old. The doctor recommended the use of pronosal one dose of aerosol in each nostril twice a day, that is, in the morning and in the evening. It is to use this for two weeks. I wonder if these are not too large doses for such a small child, if in the leaflet it is written that it is recommended to use in such young children one dose for each nostril once a day
