Uninterested Granny

If you cope you don't need help. Stop asking for it.

I think I may have worded the original post wrong. I don't expect her to be useful, I just remember growing up and seeing both my grandmothers on a regular basis and sadly for my son this just isn't happening for him.
Me and her get along really well (honestly!) so I think that just adds to the confusion of the situation.

She has probably read about 'interfering MILs' and is determined not to be one.

Cross posted but I think my post still stands.

Were you much of a friend before the child was born?
I would get to know her as a person. Leave your husband with the baby and suggest a day out for just you and MIL.
I may be wrong but it sounds as if you hadn't a relationship that didn't go through her son and now you think she can be useful.

Me and my MIL get along really well. She says that I'm the best thing to happen to her son.

We do ask her (less and less now) and I do cope. Maybe I imagined that when I had a family of my own other family ties would be strengthened?
Being around other family member I think would be good for my son with socialisation etc.

PS You said be honest: as you've put it in your post, you seem a bit selfish to me. What about considering her needs? Maybe she doesn't like travelling. Maybe she's not keen on babies (strange but possible). Maybe she hates housework. Maybe she doesn't like you much.

Why don't you just ask her to visit? Grans don't have to help you know. Some mums don't even feel they need help from grans and rather resent grans 'interfering'.

You're an adult. If you aren't disabled you ought to be able to cope with one child and any absolutely necessary housework. It isn't actually necessary to do more than that.

So, yes, I'd say you are asking too much.
