New grandparents

Sorry, I've got that wrong. She's your H's sister isn't she, that said I still don't see why her being estranged from her GC is relevant.

IMO unless your s.i.l. is unsettling your D and your D feels unable to set her own boundaries and asks you to do so on her behalf, you shouldn't say anything 62Granny.

You say she's estranged from her other GC, but as she's clearly not estranged from her son, your s.i.l., why is that even relevant?

Nothing more annoying than sitting there, big and heavy and impatient to meet your baby, and having someone constantly asking if you've had the baby yet. Like you wouldn't have told them.

62Granny, it sounds like you're trying to control your SIL's natural behaviour. I'm sure that your daughter can cope with any over-enthusiasm, so it's really not your (potential) problem to solve.

It's not a competition. You don't have automatic priority or 'ownership rights' over your grandchild. In fact, you have no rights, so please don't have set expectations.

No one can speak to what her motivations are. New babies create excitement at a level that can make even the most level headed people seem irrational at times.

It is interesting that you mention that she is estranged from her own GC and then ask if she might be trying to take over yours. Why do you think that way? One of the things I have learned in all my years is that we women do have a sixth sense and I have never heard of a women not trusting her instinct.

Honestly, your daughter is an adult and needs to take care of this situation herself if it makes her uncomfortable. If your DD asks you to intervene, then you should.

why is she estranged.
was she behaving badly in relation to her own GC.
she might need to be warned off.
don't let her bother your Daughter's family.

Gushing is not your style but it is hers, we are all different. Being estranged from her own grandchildren may make her more interested than she may have ordinarily been but what does it matter, the more people that love the baby the better.

Ooops. Sister in law.

Presumably your daughter will be able to stave off your sister? (With a chair, if necessary!)
Unless she is unable to, then I would leave it be.

How does your dd feel about this?
