A bit of an aibu and wwyd! My step children have had absolutely no vaccinations ever and their mom feels strongly anti vac. They are both now teens (just!) And I feel quite strongly that they should have their MMR and tetanus, especially as we are planning on going camping this summer. Dp feels it will just start a war with their mum as she gets very upset when its mentioned and they are getting on well at the moment. Does anyone else have experience/advice?
