Advil was made for this very reason.
Personally, I think it's all in the attitude you take when dealing with the screaming. (I wish I could scream when things don't go my way.) Do your best not to get frustrated with it. She's communicating the best she knows how. Instead, try distracting her. It doesn't always work, but when it does it is sweet relief! If she's frustrated, very seriously ask her thif you can have a look at what she is working on, then act very interested in it and give her a peek, then take it away playfully with a gasp and offer it again. Kind of like showing a peek at a lightning bug. Make it a game and then quickly introduce something else wonderful.
Boredom is easy to fix- find something that entertains you both. Babies love to watch their mommas have a great time! I read somewhere that the attention span expected at this age is around 10-15 minutes in a gym or entertainer. Short and sweet.
Until the episodes lessen, frequent family places when you go out. It's better people watching anyway and you walk away feeling like parent-of-the-year
