Hi Fergie I am so not an expert on this but let me tell you about what my DD says about her in laws. firstly let me tell you that I raelly dont agree with all the present buying that goes on these days. Children open gifts, give them two minutes attention if your lucky and they are thrown to one side and forgotten Also let me agree that the "chirpy" attitude would p... me off eventually. But we are who we are and just have to accept that. My DD says of her inlaws that they are missing out big time as they do not want to spend much time with the GC(2of them both my DD as she is an only child). Their son(my DD partner) is a very quiet lad and doesnt comment but she says it hurts him. I have to say in their defence they did have my DD the GC and their son stay with them for a year!! Brave people. They spend quite a bit on the GC we do not. We do have them for W/E's as much as we can and act daft and have fun with them. Not saying we are right and they are wrong but DD does say she knows who the children will remember and want to be with.
Even being a GParent isnt easy at times is it? Just be your nice self to your GS and he will want to be with no matter what else anyone is doing.Xto youX

You sound to have such insight into your own position and feelings but guilty for them. I think how you feel is quite natural, it's almost as if your daughter has been taken over by new parents. Who wouldn't feel the way you do under the circumstances? I think the advice you've been given by your niece and friend is exactly right and you, yourself said 'I don't want to aggravate the situation' That is a risk. It's possible your daughter is aware of your feelings already but has a lot on her plate and just want's you to be there and not say anything. Maybe she feels guilty but doesn't want any upset because that takes time (if you know what I mean) 
) and that is our special thing to do together. Currently, we can both recite 'Beauty and the Beast' word for word, including the adverts!! She then acts it out for me - such fun!
