Girls, hi. Has anyone given their kids cynabsin (a drug for runny nose and sinusitis)? Personally, it helps me a lot, I feel better on the first day. You need to chew the tablets, my son is 2.8 years old, he can't chew them, can you just crush them and give him? It turns out that he will drink it, not chew it, will there be an effect or not?
