Delaying a class for the Holidays would be a colossal mistake, IMO.

Delaying for the birth of your child may well be "worth it" (only you can decide), but, it sounds like either way your bundle of joy will be here before your class date, so you're really considering time at home. How good a support system do you have in place for your wife & new arrival?

Congratulations, both on the new job & (more important!) new baby!
