DS getting over a cold, OK to take to gymbaroo?

[Miss.B]

DS started with a runny nose and cough last Sunday. ATM he's got that dry cough but the runny nose is only present at night time (getting less and less). He's not had a temp or been off his food and is in a generally happy mood (bit clingy the last couple of days but getting better). The thing is that we have gymbaroo today and I don't know if to take him. He loves all the equipment and generally seeing the little kidlets. I myself have had a scratchy throat and chest since yesterday. Should I give it a miss? Is he contageous at this stage?

I wouldn't go if he's sick and you are too. Don't want to spread it around.
