How to relieve stuffy nose in toddlers 
Use a nasal aspirator to remove excess mucus from the toddler's nasal passages. 
Since most toddlers are not able to blow their noses, they require additional assistance in order to clear their stuffy noses. A nasal aspirator, also known as a bulb syringe, uses suction to pull mucus from the nostrils.

Available options: --Put the nasal aspirator in your toddler's mouth for approximately 30 seconds. After this, suck the nose clean until the nasal aspirator is empty. --Nasal aspirators have a bulb section and a long, narrow section you insert into the nostrils. Have the child lay down on your lap. --Choose your own bulb syringe to use if you are a beginner with your child. Warm up the syringe to its usual temperature before using it. --Its bulb contains a small film of mucus. To remove the film (from the nasal aspirator), insert your finger from the nose bud and slowly pull out the foamy particles.
The answer is:
Nasal aspirators have a bulb section and a long, narrow section you insert into the nostrils. Have the child lay down on your lap.
