Waiting for the medical and wife has got pregnant. Should I inform CHC or wait?

[manlec]

I applied in Aug 2009 with my wife and two children. Recently in April 2011, CHC London asked me to submit my updated forms and passports that I sent them in May 2011.

We just came to know that my wife is 1.5 month (approx 8 weeks) pregnant.

Should I inform CHC about this situation and ask them to hold my application till the child brith OR wait till I get the medicals and then inform them to delay the medicals to be done with the new child application?  or is ther any other better option? what are pros and cons for either of these approaches.

An expert advise is needed and highly appreciated.

Thanks
