Is there anything she is still able to enjoy? Perhaps staff have some ideas?
Flowers perhaps or music? Or visitors, even volunteers that she does not know. Or photos, which can be placed in her line of sight. . There was a bird table outside my mother's window when she was in convalescent care put there by the relatives of the bed-ridden lady in the next room.
My mum has never been very family orientated, and so is unlikely to look to me for emotional support or gain much pleasure from Grandchildren and their achievements. The latter is a real pity, but she did not invest the time earlier on when she could have done, and so does not really know them. She also lives two and a half hours away...when traffic is good.
However she is very social and gets bored quite easily. She loves her life in her sheltered housing, within a community and yet with support to cover the skills she has lost. Now things are settled there there are far fewer things that need my presence. I am lucky perhaps that I am looking after property for her, so am able to call in rather than making her the focus of my trip. I have found short visits to be a lot less difficult and probably the same is true for my mother, though the journey is a pain, and this is without a baby. She is pleased to see me but half an hour is enough. I am very conscious of her capacity slipping away and so plan to stay near her for part of the summer and taking her on outings, as this may be the last year she will have enough orientation to enjoy going out. The focus will be on things she enjoys, not about her seeing me.
If she has been more family oriented and the emotional ties were stronger I might have felt guiltier about not spending much time with her. Instead I am focussing on things which matter to her, and which I can do from home, eg sort out transport so she can get to church, negotiate a lead carer who she likes etc. When the time comes I will research the right dementia care setting for her.
This is a slow bereavement. If your mother no longer gets much pleasure from your visits, you may need to accept that this part of her has died, and that you focus on what she does enjoy. Photos, flowers, favourite things from a happier time, that remind her that she is loved.
It sounds tough. A new town, baby and a dying mother. I echo what others have said. Do what you can, but look after your other priorities as well. Guilt is not helpful.
