Hi there!
There are a few schools arnd Novena: Etonhouse, Pats Schoolhouse, Modern Montessori etc. The list goes on. I went to all these while looking for a school for my eldest child.
My 4yr old girl is currently at Learning Vision at Gentle Road (
www.learningvision.com) & I recommend it. Fees are not as high as other schools arnd the area. There are also quite a few of expat kids in the school. Your son wld either be in Toddler or Nursery 1 class. You also have option for either half or full day.
We are expecting our 28mth old twin boys to join their sis in the school soon:)
Anyways, you shd call up the schools if you want to enrol him soon. The popular ones might not have space in the school & may have to put you on waiting list. There is a quota on the student-teacher ratio for each class which they cant exceed.
Where are you from anyways?
