Although these suggestions are well meant and helpful we need to remember that the new mother is the granddaughter of Greatmama who is not really in the position to seek advice or help whilst the new mum is in hospital. She has hospital staff to care for her, possibly some support groups, there must be a dad for the baby , is he absent ? The new mum has two parents, that’s quite a lot of people to potentially help. Great Grandma can only do so much and contacting G.P. Or Social Worker would breach confidentiality and anyway not be appropriate. I am sure it is very worrying, Greatmama but sure you will be able to be more involved when mum and baby get home, if they want help.
