sick child... any tips?

Va

so my son had a cold for about 2 days now, he's in bed sleeping, but keeps waking up every 10 minutes because he has sore throat I have him some medicine to relieve the pain, but doesn't really look like helping... looks like gonna be another sleepless night, is there any other way to relieve the pain? he wouldn't take anything to drink, spits everything out, he's 1 year and 8 months
