Yet another round of: pay debt or invest?

My wife and I have $23k left to pay on consumer debt with 5.5% interest. I'm about to start working in a month or so and boost our household income from $80k to $130k in a LCOL city. I was going to wait to put our baby in daycare for a few months so we could pay down debt aggressively and have it paid off by the end of the year, but would it be better to invest however much extra we can in our retirement accounts? If we're not paying down debt aggressively, we'll probably try to find daycare sooner.
