My mum's best friend is dying and I don't know how to help her and her children

[Rosa343]

For those who have lost a loved one, what did other people do that really helped you? xx

I think it is specific kindnesses rather than general “call me if you want anything”.
Perhaps practical things -
Providing general meals that can be heated as required. Cakes. Teabags, coffee, even loo roll!

Facilitating them getting to see their Mum, if that is what they want to do - have they got an Uber app or could you set one up?

Childcare if that’s appropriate, walking their dog, feeding pets etc.

Also, just being there for them if they need to cry or rage at the unfairness of it all.

Whether they want or need assistance with the practicalities once your friend passes is something that’ll become clear nearer the time.

'I'm going to the supermarket/passing the pharmacy, can I pick up anything for you?'
'Can I drive anyone to/from the hospital/doctor?'

And end messages with 'No need to reply, just letting you know I'm around.'

And don’t forget your Mum and yourself in this; you may both need to spend time with her friend.
She needs to know your Mum loves her & appreciates her friendship & always will.
Your Mum
may need a place to cry & rage too.

Are you someone that they know well enough to accept help from? I only say this as it's your mum's best friend, not your best friend.

It's very common for the person to be very very tired and family to start limiting or stopping visitors as it's too exhausting.

If you are close enough then childcare, dog walking, being available to do some of the endless runs to the pharmacy are all really useful.
