From what I have seen in family law court...
(in CA)-and I tell ya, my brothers case went on for DAYS just waiting to be heard, so I got plenty of listening time for other cases...
Yes, I saw lawyers say those words, "I object" and in some cases, the objection was heard right then, in others, well, the judge politely told them to wait their turn....
From the pro se cases I saw, the judge got really upset if one party interupted another----and then, really, really, really, upset if he/the judge was interupted.
So, my advice would be wait your turn to speak, take notes, etc..and when it is your turn, then you can refer to whatever you are objecting to.
Also, the judge I watched, if one party made claims (for example, "he's an alcoholic...." etc....), the judge listened, but I dont think it carried much weight. Now, if there were declarations filed, (for example, my nieces mother filed a declaration stating we were all excessive smokers in my home....she's never been in my home, and we had quit smoking at least a month before this filing) the other party has to have a copy and the judge does read it--then judge questions each party.(smoking thing went no where..btw)
Another suggestion, if you can...get to the court house and observe your judge before your case comes up...you'll get a really great idea on how to handle things and the judges temperment, etc....my husband and brother had the same judge, even though they were different courthouses...I knew the minute we walked in for my brothers case that he was a fair judge and looked out for the children in all matters....no matter how many "objections" the other party tried.
good luck...
