If you do enroll your girl to childcare, you will be look at infant care services which usually range from 8 week old babies to 18 month old.
Fees would very much depend on what center you choose and to be entitled to the subsidy you would need to produce your payslip or your CPF contribution printout. If you do not have it at the point of registration, you can produce it when you get your first payslip to the center and they will help you apply for the subsidy.
Usually upon registration, you would need to pay a 1 month deposit + fees + uniform/bedsheet fees.
Most centers will go along with your timing for food feeding. They will try as much as possible to adapt to your routine. But once my boy was 13mths, he was "upgraded" to the older infant group where they nap together at a fixed time and ate together at a fixed time. This was good for him as it helped him transition into playgroup at 18 mths.
You'll need to shortlist the centers you want to visit and personally make a trip down to look at the environment. It'll be good to go during a weekday, eg 10am or 3pm, where most kids are awake so that you can observe the kids and teachers in action.
Some centers have "curriculum" for the infants though I find that it is usually not followed through. But my son did do some arts and crafts in school like hand painting, pasting stickers and stuff like that to enhance the fine motor skills.
In regards to food, you'll also have to check with the center. Usually they have a menu for the kids too which is repeated monthly.
Most importantly you must like what you see. If the environment is out of control, smelly and dirty, chances are your girl will not like it there.
There's a Cherie Hearts at Paya Lebar area. It is not too bad. You can also go to the MCYS website to do a search for centers with full day infant care services in the desired area.
