I wish the baby would stop crying

[Boris Tatarenko]

Let's pretend that we hear a baby crying. It's been crying for a long time and we're trying to concentrate on something but it's literally impossible because the baby is distracting us. :-D

Is it all right to say:

1) I wish the baby would stop crying
2) I wish the baby wouldn't cry
3) I wish the baby wouldn't be crying right now

I'm pretty sure the first one is idiomatic but what about the other variants? Which one is correct?

They all lack a full stop, Boris. The first two would be OK with full stops. The third one would not.

I think the third would be OK if 'wouldn't be' were replaced with 'weren't'.
