Hi Vanitykills, punggol area childcares are horrible as everywhere is packed.
I live in punggol too but lucky for me is my son is staying at my mom's place at bedok reservoir road on weekdays and i place him in childcare near my mom's place. I place him at Raising Champions Learning Cove at Kaki bukit.
no need to fight for place for punggol and sengkang always in waiting list. and its very frustrating too.
If you are working near bedok maybe you wish to consider the preschool i mentioned. they do not have website. if you want i can pass you the contact and you can ask more about the school from the school teacher.
