Granddaughter showing preference for other grandmother and ignoring me

She has the advantage of being a novelty and perhaps seems a bit "exotic", but as others have said she will soon be hundreds of miles away and your normal relationship with your granddaughter can resume, as long as you keep your feelings to yourself

Awww FloraRose you sound so upset.
I'm sure things will settle back down again when the other grandma returns to Australia.

Try to pin a smile on your face for now and don't take it to heart.
Maybe take a step back and don't go on so many of the outings, let your granddaughter have some 1:1 time with her other grandma.

This lovely lady's time with your shared granddaughter is brief, so be glad for them both that they can enjoy each other's company for a few short weeks.

No child will respond to the sense of ownership you demonstrate, and you will experience more hurt if you expect so much. Love her and enjoy her and your relationship will flourish; anything else and you will damage what you have. You may feel hurt and excluded but as long as the child is not actively rude you are best off saying nothing and leaving her mother to do any necessary talking. And sadly she is not your girl.

It’s a fascination with something new. Someone different to talk to. A grandparent who hasn’t been seen for ages and suddenly appears. Please don’t take it to heart. I know you’re upset but the other grandma will be gone soon and the novelty will wear off.

Im not being harsh but I assume that the other GM is going back to Oz ? So if you bide your time and just try to keep the relationship ticking over your relationship will hopefully return to as it was shortly . We can all be guilty of being swept along by the novelty of a seemingly more interesting visitor from afar . Just take a back seat for a while and be careful . I hope your relationship soon evolves into a new special bond .

I think you’re overthinking this and taking it far too much to heart. If her other grandmother lives in Australia and she doesn’t see her often it’s a novelty, so of course she will want to spend more time with her, and it’s nice for them to have time to bond. Don’t be jealous, or at least don’t show it, or you may permanently damage your relationship with her. There’s nothing wrong with her being close to both her grans.
