Spend it on childcare!
Wherever you are from, childcare is ridiculously expensive in the US (compared to German child cares). But for us it is worth it, as the kiddos not just socialize, they learn English as well. In fact, my older son is already more fluent then I am and he is just 3.
Kudos though to parents who are willing (or unwillingly willing) to stay at home with the kiddos. I stayed at home with mine a year each. After that I needed a break.
Save for retirement!
I am curious on how you are taking care of your future.
Invest in your career
I know many spouses who take evening classes either in their field of work or field of interest or you are inclined to finish a master’s program?
What are your plans for your tax refund?
