ill child and wedding attendance

[cottonreels]

My Ds (18mths) is ill with tonsilitus which started Monday night. The doctor yesterday, when prompted, said it would be infectious. He is clearly unwell but perks up with paracetamol and nurofen and is on amoxicillin which will hopefully help him soon.
Tonight we are travelling 3 hours to a wedding which, will take place on saturday, and helping with wedding preparations. The bride is my DP's twin sister, so we'd obviously still like to go, though I think some of our help may now be scaled down.
My Dp's other sister will be at the wedding with her 3 dd's - one who is just 4 months old. Her reactions to this like this can be a little unpredictable and communication in the family is not great where people say one thing but mean another.
Im sure there'll be other children too who we don't know. There are no old/frail people attending.
My DP points out that we have both gone to work in the past with infectious illnesses (like colds) if we've felt up to the job, and therfore exposed others to illness. He thinks this ocassion is no different. We live in a world of germs and if you don't want to be exposed to them you stay at home.
I do sort of agree, but can't help being nervous of the baby catching it and also, if Im honest, Im nervous of what people will think of us- both in exposing others to it and taking our ds into the ceremony and a party atmosphere (though he will be well looked after with lots of relatives, and will be ill wherever he is regardless).
What do you think, would wbu to take him? Really don't know the protocol.
Do we warn the bride now that he's ill even though the build up to a wedding is a stressful time and he might be feeling a lot better by then?

'We live in a world of germs and if you don't want to be exposed to them, stay home'

Great attitude there - very socially responsible. So when your child has CP or D&V, you'll still be sending them to school and it's up to everyone else to keep their kids at home ?

You very clearly have no intention of missing the wedding so I'm not sure what the point of your post was. Apart from being able to justify your decision to knowingly risk passing an infectious illness to other kids becasue some random internet strangers say that you should ?

if you know your child is sick, and possibly infectious, you have a responsibility to protect others. you cannot possibly know the situations that others are in, hotel staff could have immuno-suppressed relatives or not receive sick pay for all you know and would really not thank you for knowingly infecting them.

It is a difficult one but I would err on the side of caution - talk to the Dr about the contagious period.

At my wedding 8 years ago 2 separate friends came up to me bearing children who they then told me had been throwing up all night!!! DH and I were due to fly out on honeymoon to the Caribbean 2 days later and I spent most of that time praying that we hadn't caught anything - especially as one of them was trying to get her DS to kiss me! I was pretty peed off about that TBH as they really shouldn't have brought them to the wedding....
