AIBU not to know how to sign off on a card to son and partner?

[VioletSky1234]

Silly question I know, but my son and his partner have moved in together. I want to send a card/flowers but how do I write the sign off on the card..From mum (I am not very close to his partner as they haven’t known each other long) or my name? Or mum (and my actual name in brackets?).

As they haven’t known each other long this hasn’t come up before!

Please help 😀

I would sign 'Mum/name'

we get cards saying love mum/granny/first name and dad/grandpa/ first name. It’s a bit clumsy but he ho.

Just put mum

To both, I'd just say Mum.

If only to the partner then to the name they use for me
