Hi, we took our test in December last year. Our son was 9 months old at the time. We asked one of our friends to accompany us to the testing site. Our son stayed in stroller with our friend while we took our test. There was a waiting area outside the testing room for those waiting for the interview. Nobody raised any issues. If possible, find a friend. Otherwise, you'll have to leave your child in a day care for a few hours. You can't take your child with you in the testing room. That is strictly prohibited.
Good luck.
