If is urgent its better to post an ad in Gulf Times news paper (lucking for nanny) its around Qr 100 per day you will not need more than two days and for sure is effective you will be getting many calls.
Now if you are lucking for a day care wakrah is the wrong place, lol.. I live in Wakrah aswell and this is one of the things we need here.
P.S: do check the Independent Schools Maternity, there are lots in Wakrah (there is one behind the stadium on you right inside)
