My Dad has dementia and my Mum is his carer. They live round the corner from me but I have hardly seen them in six months although I do keep in touch. I have been following the rules quite carefully as DH has underlying conditions which mean he may be quite ill if he gets Covid although he is currently quite fit and well but very anxious about the virus.
My Mum is struggling mentally and emotionally and needs more support than just a phone call. She is worried about what would happen to Dad if she gets ill although I have assured her we would find a way to take good care of him. She also misses having company and says that Dad likes having people come round even though he doesn't say much. He is deteriorating quite quickly at the moment and she thinks this is partly lack of stimulation. They get out of the house now and again but Dad can't walk far and Mum struggles managing his wheelchair.
My question is would it be unreasonable for me to visit them both now and again under the exemption of 'caring for a vulnerable person' providing I follow social distancing rules.
