should i update my w4?

My wife and I file jointly. When i started my new job, I did not fill out or check off step 2 because my wife works. Also last year, we had a baby. Should I update step 3? But I want to make sure my wife and I do not end up owing. whats the best way to make sure we get the maximum refund?
