@alayna22, My son does the same thing too even when I'm talking or something lol

Just ignore it as you should do with tantrums. They want attention. Also, if you yell back it shows that you yell so why can't she? And it also may upset her if you yell which can, in return, cause more yelling. And she's ONLY 10 months old... They're just learning so it's going to happen, don't get upset just stay consistent

don't give her the reaction or attention she wants at the moment she is screaming. wait for a break in between where she is calm and collected (even if it is a 5 sec break, you just have to catch it quick enough) and then respond to her then. if you keep this up she will soon learn that you will not give into her when she screams. it's hard at first, but after a couple days it gets easier

Well when you scream or yell no it probably sends the message that screaming is okay, or she interprets it as a game of who can scream the loudest. First get her attention and then in a firm, strict voice say no. The yelling no is probably only going to make her scream more and louder.
