I've done the course and I wouldn't be happy with a baby in the classroom..being breastfed, winded, changed etc etc.
You have to concentrate! And you are there to learn. There are strict rules about mobile phones being switched off for that reason. There are group discussions, flip charts, and a good few hours of listening to the instructor. You take a test which is at the end of your workbook to make sure you have been paying attention and the instructor signs off your workbook to say you have completed the course and he is satisfied that you have participated and gained knowledge through completing and attending the course.
A baby present would be a huge distraction and it would be totally inappropriate. Would a baby be allowed to be present during an exam? I think not.
