My baby is 8 weeks old now. Till now I have kept the policy of not letting people who just travelled abroad visit our home. My husband’s brother and his wife just came from their trip to Spain. (We live in London btw). They are planning to come home tonight to watch the Euros. I am a bit excited for adult company. But worried about exposure of viruses to the baby. Should I let them come? Maybe keep the balcony door and windows open? Or better to not take risks?
