Screaming 8 month old

My 8 month old has discovered how to scream. He's not screaming because there's anything wrong, I think he just realised he can make a loud sound and he does it, often lol he's a very social, talkative baby so it's another way to use his voice I guess. But when he does it in public, people glare, and if he does it at home too much I worry what the neighbours will think!

Im assuming this is just a stage? Please tell me they stop it lol

I know what I would do to cope with it with a toddler, but Im unsure how to handle it with a baby.

At the moment I am just saying 'no' in a stern voice when he does that, the same voice I use when he goes to something he shouldn't touch (he's crawling and getting into everything). He has started to understand no with the touching things, but he isn't applying it to the screaming.

If I ignore him so far he just keeps doing it... I try distracting him with something else to do which sometimes works sometimes not.

He does also scream sometimes if he's standing up somewhere and can't get down or if you take something off him he wants lol... but I think that's because he's clever and he knows he gets attention if he screams.

Aside from the obvious headache of hearing it all the time, Im worried he will get a sore throat or aggravate his reflux which is quite bad.

Any ideas/suggestions? Thanks
