it's all depend on the race type.
chinese is expansive usually range between 1000-1500/mth weekday
malay and indian is cheaper, from my friend they said range around 400-800

if you are finding those at home one nanny jaga 1-3 kids sure expansive
private child care centre is expansive also, asked before around 2k

there are child care centre like those near gomen work area will be cheaper. i think 400-800 also. like taska qistina those u can try look around. these type macam jaga froom 3mths old to 4yrs old.
