Re: 8 month old waking every hour or two at night
How common is this? So common. Common as dirt. Especially during teething, which I am sure your 8 month-old is doing. But you may want to get his ears checked, too- perhaps he has an infection.
"Just let him cry" is terrible advice, particularly for a baby under a year old. I know plenty of people use cry it out methods, but they aren't right for all families and if they aren't right for yours, people shouldn't be pushing them on 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!"
