As most ceremonies are public and you can bring guest (although sometimes limited space) I can not see why you can't bring your baby with you. There should be no problem.
How in the world would you ask such a question on here? What if someone mistakenly or deliberately says yes you can although in reality you cannot? What will you do when you show up on the test day and you are told you cannot bring in your infant? Come on man, contact the right authorities for your own sake. People here give random answers based on opinion!
