Hi,
Here is the link i found to look for daycare in your area. it actually allows you to look up by postal code. It belongs to the Ministry of Community development.

Now, I live in Bukit Batok, and have searched the area throughly. I am afraid I must have very high standards because there has been not one daycare that I found comfortable with. The only one that appeal to me was Learning Vision at NUS, but it it way too far for a daily schedule. You may find another post I did on this matter. Let me know which daycares are you considering and I will give you some feedback. Also, note that MOST of this places have a long waiting list and they make you fork out an average of $600 of deposits after registration, even if you only want your child to attend one day a week.
Good luck,
Paola
