EC only works if parents are the sole carers, and every success story I've heard had one main parent doing 90% of the care-taking. No daycare would do it, and if you can find a nanny, au-pair, grand-parent or other carer who is up for it ... small kids still just behave differently around different people. If they have a different level of comfort, anxiety, or reluctance with a person it breaks down.
