Re: 11b Questions
Your wife does not need to be there so that is irrelevent unless you want her to take the stand and testify. Since I believe you do want her to testify, you can ask for an adjournment because she is about to have baby, but then that delay will count against you and will not count towards an 11b application.
If you can get an adjournment because they did not give you disclosure, then that would be preferred because the delay WILL count towards an 11b application.
So you should save the "my wife is having a baby" thing for the last option that you bring up.
