Frankly speaking - it depends on if the IFC even have availability for you in the first place. I would call up the centers and find out which ones have slot. I had to be on waiting list for 6 months!
Also are you looking for full day infant care of half day infant care?
For full day infant care there is only 4 centers in east coast area. The schools u mentioned above is for preschool - so 18 months and above.
For infant care you have these options
1. Odyssey - gorgeous but very very very expensive. This is at still road
2. My first skool - Good school and curriculum. Located at Marine terrace.
3. Babyplanet montessori - Siglap. This is the most affordable at $1,600 a month, and under $1k after working mothers subsidy.
4. Bibs & Mitts - East Coast. Also offers half day on Sat.
