Hi - DS (4) has had a cold since last week and I have sent him to school - he really wants to go and as he was fine except for runny nose I let him go. Now cold is at the chesty cough/blocked up nose stage. Is there any point in keeping him out of school? He is desperate to go and my feeling is that he got the cold in school anyway! And it was contagious at the beginning not now.
Advice??
