Is it advise able to send lo to infant care? Any recommendation of infant care? How early do we need to start queuing for infant care / care child?

My little on has been at IFC from 3 months - I am really Glad we did it. We are both full time working parents, so we don't get to spend much time except weekends with her. So I credit a lot of her academic development to her infant care. At 17 months now she's really friendly with no stranger anxiety and she's talkative and is able to do things a lot of kids her age can't. like she's comfortable being centre of stage and presenting to people (as school does show and tell), dancing and singing (she is able to sing along to twinkle twinkle and show the actions of head, shoulders, knees and toes song), running, jumping, climbing and she speaks English but understands English, Bahasa indonesia and mandarin well. She goes to a Montessori infant care school.
