I really feel you on this, being a first-time mum and trying to find the right infant care is so stressful. I don't have personal experience with that specific centre, but a friend of mine did enrol her child at an E-Bridge centre and she said the teachers were really attentive and caring, and she felt quite reassured leaving her baby there. It might be worth visiting the centre for a tour so you can get a feel of the environment yourself lah. Hopefully some other mummies here have more specific info on that Bukit Batok branch to share with you.
