I noticed that my 9mth old baby has been coming home with occasional bruises from infantcare. I checked with the teacher and she got very defensive and said that she;s not sure how he got it. What do you think I should do?

I think you should speak to the Principal. Find out whether the centre has CCTV and demand to see the past videos of the day your baby came back with bruises. Bruises are very unusual for a 9 month old baby. I really hope the centre will be open minded and objective here. You can also choose to make a police report and inform ECDA (the governing body for infantcares).
