Hey there! So, we have a wonderful daycare picked out for LO, but unfortunately we found out that instead of her being able to start in September or early October, it's looking more like January of 2017.

I am very disappointed, as our plan was for me to go back to work in mid or late August, and my mom to come down and watch her for a month until we could get LO into daycare. However, it'll be too much for my mom to watch her for four months and I can't go back to work later than August, so we're going to have to hire a nanny until her spot in daycare opens up. Since this wasn't part of our original plan, I'm feeling a bit out of my depth as far as a few things and wondered if any other moms who are using a nanny or have used one in the past could answer a few questions:
1. Did you use a nanny service to hire your nanny? If so, do they charge a fee on top of the nanny rate? If so, is it one time or monthly? If it's a national (or local to Southern California service) and you liked it, let me know!
2. If you did not use a service, other than doing a background check and requiring certification in infant CPR, was there anything else, credential wise, you insisted on? Did you require proof of the infant CPR? (Like a certificate or something?)
3. Holiday pay - unfortunately in my industry, we time off but no pay. So, I'll get a week for Thanksgiving and two weeks over Christmas/New Year's. Is it okay to just say we won't need her those three weeks? Or should we offer her half (or full) pay even though we won't need help during those weeks?
4. Do you pay your nanny in cash or check? How do you handle taxes? I heard there were some programs you can use to deal with taxes (both yours and the nanny's) if you use one of those, any specific recommendations?
5. *Edited to add* - What questions would you ask in the interview? Obviously, I'd want to hear about their nanny experience, get any references and see what their personality is like, but is there anything specific you would ask?
Thanks SO much! Also, if there's anything else in terms of advice or info, I'd love to hear it!
Re: Nanny questions
We use a payroll company. I think they're pretty pricey, but my husband didn't want to mess with figuring out taxes and whatnot. We actually got direct deposit set up, so the money just transfers from our bank account to hers every week. For such a short time, I wouldn't go this route, but it is an option.
If you don't use an agency, be sure to do a phone interview first before you invite them for an in-home interview. Having each of our interviewees handle our little girl was probably the biggest deciding factor for me. We interviewed some great nannies, but one lady looked so much more comfortable handling my baby. I knew I'd be ok leaving the house with her in charge. Like @stephanienjer said, it'll feel right with you've found the right one.
Even if you don't use them, care.com has some good information about hiring. We used their list of questions for interviewing.
