we had a similar thing and everyone started asking the question but the thing is once you have the bub - people will ask when the next is coming.... its never ending!

We always told people (and its the total truth for us) that we had planned to do the kid thing before marriage so we can have our kids actually in the wedding - making it a real family day- now we have been engaged for a year and the pressure is now on us to give a date for it! We are in no rush though... we have happy as is and it will happen one day!

Just know that what you do it up to you and therefore cant be wrong if it makes you guys happy
