My 15-month-old has a bad cold and sleeping is very difficult because his nose is very stuffed aside from using the nasal aspirator, what else can I do?

In addition to using a nasal aspirator for your 15-month-old with a stuffy nose, you may want to try using saline water ampoules to help loosen the mucus. Unfortunately, there are limited options for treating a congested nose at this age. One option is Helexia Prospan syrup, which is an anti-mucus syrup made from dried ivy. It can help with coughing or thinning nasal secretions. Another option is using homeopathic syrups like those for 0-9 years old or honey syrup, which may help clear excess mucus. These are some possible solutions to consider.
