High pitched screaming ??

My 7.5 month old boy, the last few days he’s just randomly screaming high pitched, not in an upset way or frustration, like he’s either trying to be (annoying😂) /funny or he’s just learning what his voice can do? At the moment he hasn’t done it in public but he does use his voice quite often in some kind of way, I just don’t want people to think the wrong thing like I’ve hurt him if they don’t see me/his dad and him 🥴 Quite a few friends,family & even members of the public come up to us and have commented on how vocal he is for his age. FTM so unsure if someone thinks he’s “advanced” in the speech department as my cousins child is 10m old and he’s a very quiet baby according to them and found it unusual my son was so vocal for his age. He just doesn’t keep quiet all day, which is lovely to hear and I’m not complaining, I love seeing him develop 💙
