Should I Start Collecting Travel Rewardingly or Wait?

[Will Crocker]

I am about to close on my first duplex and will be having some expenses coming up to do some minor repairs, however my wife is also about 4 1/2 months pregnant and dont see us traveling much in the next couple years because of that. Should I start collecting travel rewards now and risk them expiring, and wasting opportunities for Southwest’s buddy pass, or wait until we start traveling again to focus on rewards points?
