Well the rest of US really enjoy your pleasant helpful disposition.
Some babies don't sleep. Sometimes, there's just not a solution and you have to wait it out. It sucks, but there it is. No amount of CIO or co sleeping or bedtime routine or going to bed early or staying up late or white noise machines or anything else help. I mean, I guess I could've just stopped responding but that wouldn't have made my baby (or two year old) stop throwing up or screaming...and it would've made me a pretty crappy mom.
