My son has what I think is a chest infection. Only GP appointments are school hours and I'm a teacher (and has to ask for time off for two other things recently) My husband is away at the moment. Would it be unreasonable to send him alone? He's an articulate capable lad. I'd collect any meds after work. He's at home off school alone and I pop in at lunch. He's happy to go and it's only an 10 min walk
