Hi Andy
Firstly congrats on the impending arrival. Secondly, talk to your bank/financial institution. Some offer what is termed a ‘Pregnant Pause’ or ‘Repayment Holiday’. The interest is capitalised over this period but sometimes it will simply see you through. As a manager with a financial institution, I can tell you that clients often don’t approach for fear of being turned down, Threatending to refinance elsewhere usually gets you somewhere also.

Good Luck
