My son is almost 5 months and in the past two months he has always been drenched in sweat even when he is awake and just sitting should i be concerned?

SWEATING: It really depends under what conditions he's sweating. Kids have a much faster metabolism, so they heat up nicely. Sweating is then a sign that their body is functioning well and doing its job to cool him down. That's not a big deal. I think most kids wake up sweaty during the summer or even in the winter if you keep it very warm inside. However, if he's sweating under cool conditions, talk to his doctor. He could have overactive sweat glands or some endocrine issues. But remember, kids do three times the work to move like we do, so they sweat more during normal activities.
