21:32 here again. Forgot to mention re: the one month prior to the nanny share starting full time - You may want to pay the total amount, or at least close to it to attract stronger candidates, since many nannies will pass on a job that offers, for example $3 or so less, that first month. We were in a similar situation, and we just went ahead and paid the two infant rate for a month (the other mom - since she was already paying for that month - would drop her infant off from time to time even though she was still on maternity leave). PP, you may already know this, but if not: Here are some other things to take into account when you are calculating things - workers comp insurance, taxes, health care contributions, payroll services, and bonuses, etc. With all these costs we pay about 27k (for 45 hours a week at an average of $18/hour, split to 9/hr per family). The most expensive daycare in DC probably would be cheaper

But we really love our share!
