Let me ask, if you were a doctor, say performing surgery would you take your baby into the operating theatre?
Wouldn't you need your full concentration, aren't you determing the outcome of a persons LIFE, not to mention the effects on their family? Would it be appropriate to stop to feed. What if baby gets a stomachache mid surgery, would it be ok to stop it and have to get someone else to come along to finish your job?
I don't think that this has anything to do with excluding women from court rooms. I think this is about it not be appropriate or FAIR to the criminal justice system to not have a jurors FULL attention. Yes maybe you would have a quiet baby happy to nestle under your shirt the whole day, but would you really honestly say your baby NEVER cries, has a nappy needing to be changed, wants cuddles and attention? Would it be fair on the trial to expect it to stop for you and your baby? Would you be happy if you were the one on trial with this arrangement?
Of course if a woman with a small baby can arrange the childcare etc and wants to sit then she should be more then allowed to do so, but I don't think that a court should be required to accomodate her if she wants/needs to bring her baby to attend. It, imo, belittles the seriousness of court to expect that.
