Waiting11 - There's going to be a huge delay because you will need to submit another application for the baby and that will take longer. My advice, if your wife gets the visa in the next 2 months, land here and then go back before she is unable to travel. I understand that your wife probably wants to be with her family for this, but you guys are going to have to make a choice.
