Re: So ready to give up....
When my younger child was born, we felt very lucky to have what we called the "Big Sister Show" on all the time. My younger daughter was never bored! Except during nursing time- then the Big Sister Show could be a huge distraction, just when I wanted my LO to focus!
I agree with the PP that if TV is what gets you through this period, USE IT! And don't feel guilty about it.
Can you get your ODS into a preschool or summer camp program, maybe just 1 day a week? Or get a sitter for a few hours a day, maybe 1-2x per week? It can be really helpful to have some time that is reserved for mommy-baby, and to let the toddler stretch his independence a bit, not to mention to have someone else tire him out for you!
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
Coolest thing my little girl sang recently: "I love dat one-two pupples!"
