The key to this will be firstly resettling yourself and your husband into your separate lives, and then working out what you can afford to offer each month. Given the amount of change you are currently going throughm with a young child, it is not the right time to be thinking of committing to a fairly rigid repayment plan.
My advice, for what it is worth, would be to consider a short-term DMP until you settle down and then really decide whether an IVA is viable. This ought to remove the immediate presssue from creditors, and allow you to pay an affordable level of repayment. At that stage you should seek the advice of an insolvency practitioner who can discuss all of your options with you.
May I take the opportunity of recommending Andrew Graveson of Brightoak to you, who is a DMP specialist and enjoys a good reputation in this line of work. You can find his details on the experts page.
