I am also due in May! and am looking into nanny share and in-home care. I've hit a lot of road blocks looking this early...even though I was told to start looking as early as possible. I've found that holds true if you are putting your infant in a center however many in-home places don't know this far in advance if they will have room. I live in Elkridge and am also looking for part-week only care (tues-thurs) starting the first week of September. Have you had any luck with finding someone?
No luck thus far but can't say I've searched hard. I just find it hard to believe that someone will know in 6-8 mths what their schedule / capacity will be. I'm definitely looking to possibly drop my little one off for interaction with other little people. I'll keep you posted on what I find.
Re: Nanny Share - Too Early!?
I use to be a nanny in Baltimore and have done nanny shares before. Sometimes you can find a nanny interested in taking on another child! Good luck!
