you’ve probably seen this re criminal proceedings
Going to Court as a witness
If it’s a criminal case you’ll swear an oath on a holy book depending on your faith or affirm if you aren’t religious. You’ll then be asked questions by the lawyer for the person on whose side you’re appearing which will be designed to elicit your account of what happened. That’s called evidence in chief. You’ll then be cross examined - asked questions - by the lawyer representing the defendant- then the lawyer for the prosecution can also ask any further questions arising from that - known as re examination. If you’re giving evidence for the defence then it’s the same as above but the other way round and prosecution will cross examine.
Whatever the type of proceedings there will be someone at Court who can show you where to wait etc. You can ask for a rough time estimate and explain you have a new baby so that you’re not kept waiting around. You could ask if it’s possible to attend via a video platform the Court may be able to accommodate that.
If it’s a civil trial you don’t give evidence to elicit your account; any witness statement you may have given will stand as your evidence in chief and then you’ll be cross examined.
it won’t be an aggressive or unpleasant experience - don’t worry. Judges are very alive to witnesses being questioned aggressively etc.
Please also bear in mind that if it’s a criminal case the defendant could plead guilty and you won’t have to attend at all, unless you’re a victim and want to or if it’s civil there’s a huge possibility it’ll settle and you won’t need to go.
if you’re a defendant/claimant you can seek information from any lawyers representing you or form the Court itself.
Hope this helps but if you have any more questions just ask and I’ll post later when I can.
