DH does not want me to take our 6 month old to a mother/baby group because several of the other babies that will be there are not vaccinated.

He read an article about whooping cough in the Guardian this morning and is worried DS will contract something.

Is he being unreasonable?

My goodness, the thought never crossed my mind when I took DC3 to the church toddler group when he was four days old.

Yes he is. As many other posters here have said, if your DC is vaccinated what's the problem? You can't shut out life for the sake of bugs.
