Shouldn't the 3 Idiots have been certified 'A'?

I write this from the perspective of a mother of a six year old. Who came upto me yesterday and asked me, mamma, what is balatkaar? I had no reply. It was not something I wanted to explain to him. Not yet. I'm still hoping he will stay safe knowing to differentiate between good touch and bad touch and hoping he never needs to experience bad touch.
Lets take the film from the very beginning. We see Madhavan pretending to have a heart attack to have a flight return back to the airport, in order to follow a trail leading to Aamir Khan's character, Rancho. The story then goes into a flash back to the engineering college days, where Madhavan, Sharman Joshi and Aamir Khan studied together. My next painful scene was the ragging scene. A whole lot of regular guys, totally unbuff, in their undies can be a bit grating on the eyes. But what was really painful was the scene where Aamir Khan rigs up a device to electrocute a senior pissing on his door. Many male members of the audience winced collectively at the scene. Luckily the brat was too young to figure that out. Then came the scene of Joy Alvares committing suicide. Just a moment ago the boy was strumming a guitar and singing. The next shot shows him hanging from a ceiling fan. Some scenes later, Sharman's character attempts suicide by jumping from the 3rd floor. The brat is wondering what makes them want to kill themselves. The pressure of studies. This is not something that mamma wants him to think about right now. This is not something that he needs to associate studying with. Suicide is not a nice thing. Once is enough. Twice is too much in the span of a single movie. Yes, there is violence in the superhero movies he watches. But this has affected him deeply. In the superhero movies he understands the violence is fake. Playacting. In this, he knows it is based on reality. It scares me. I dont want him to be thinking that suicide is the easy way out. If you dont score in your examinations, you have the option of hanging from a fan or jumping from a window and ending it all. I agree, some of the films out there with UA certification have much more violence than is seen in this movie. But these suicides (one an attempted suicide) are disturbing. Especially the brat asking me, if that was Raju's blood from his head on Aamir Khan and Madhavan's tshirt.
And I forget Chatur's speech. The one that introduced the word Balatkaar into the brat's vocabulary. And follow this up with the childbirth scene. With animated diagrams of the baby in the womb being suctioned out. With a modified vacuum cleaner. Which leads the brat to taking out the nozzle of the vacuum cleaner once we reach home and trying to stick in inside my top to bring d baby oud. And me explaining that to begin with I need to have a baby in my stomach before the baby can be brought out with or without the vacuum cleaner. I think there is time for biology classes yet. I dont want to get graphic about where the baby comes out from. I'm still queasy about it myself.

In all fairness, the film has a UA certification. (Vidhu Vinod Chopra Productions' Rajkumar Hirani directed, '3 Idiots', has been rated as a social and granted a UA Censor Certificate (C.C. No. CIL/2/164/2009) by the Central Board of Film Certification (CBFC).This does mean that parental guidance is advised for children. Therefore, I do think it was my job as a parent to check this movie out before I let my child see it. I did not do my job. Therefore it is pointless to state the film should not let minors in. I was given the option of noting it had a U/A certification and decide whether or not to drag the brat along to watch it.
(Edited to add: This is the kind of rating system we should have here in India as well.
MPAA movie ratings are:
G- General Audiences (1968-present)
All ages admitted
PG- Parental Guidance Suggested (1972-present)
Some material may not be suitable for children
PG-13- Parents Strongly Cautioned (1984-present)
Some material may be inappropriate for children under 13
R- Restricted (1968-present)
Under 17 requires accompanying parent or adult guardian
NC-17- No One 17 and Under Admitted (1992-present) )
What has exacerbated the debate is the fact that cases of children committing suicide have been on the upsurge over the past week or so. A child has committed suicide in school. A 12 year old went into school and hung himself. My intestines twist at the thought. It might not be the movie. But the coincidence seems too strong to ignore.
The film might be a good laugh, with a message pushed in about not following the system, and learning for the sake of an education and not just for marks, the cheesiness might be a tad overdone but we accept it in good faith and laugh at the Silencer moments of odious farting in good spirit. But I still maintain the childbirth scene, the suicides and the electrocution scenes should come with statutory warnings. Close your kids eyes for the next five minutes. And yes, close his ears for the balatkaar speech. What the hell. I would have been better leaving him at home. There's time for him to figure out balatkaar.
