Great suggestions and advice girls
The activities issue isnt a factor for me because they may very well not WANT to play a sport or something once they are old enough outside of school; and considering there would be 6 of us Im sure we would get enough exercise playing 3 on 3 basketball or footy at the local grounds for free. Esp having atleast 3 sons. So there again clothing and the like can get passed down.
Dh earns a decent wage and being in the military we get cheap housing and atleast a 4bedder. The only real expenditure would be a new car if we cant get seats added to the Kluger. I already cook a bucketload of food to feed them all so I doubt one extra mouth will be an issue.
As for holidays and stuff; being military we get free holidays by moving around the country so thats taken care of
