have it both ways etc.

(1) For many women, it is still difficult to be a worker and a wife at the same time.

They can not have it both ways.
OR
They can not have their cake and eat it at the same time.

I think we can put this way, but what about the following case?

(2) For many women, it is still difficult to be a worker, a wife and a mother
at the same time.

(a)They can not have it three ways.

(b)They can not have it all ways.

(c)They can not have it all.

(a),(b) and (c) are all OK?

Also, is there any idiomatic expression that stands for 'we can not do X, Y and Z at the same time' or 'we can not do more than two things at the same time'?
Thanks.

C) is fine. I also think you can use 'both ways' with three things. I wouldn't use a).

[peppy_man]

tdol, thank you.
Let me confirm one thing.
What about the (b)?
Is 'They can not have it all ways.' fine?

[Tdol]

It works for me.
