She slept through the night from 2-4 months and starting waking up at 4 months. Numerous things happened at that time: shots, solid food, teething, ear infection, cold, etc. I don't know maybe the mixture of all that got her into the habit. Last night was the worse by far. I didn't get to sleep until 3.
I refuse to let her cry it out, so I'm reading the no-cry sleep solution for the second time. This time I'm taking it seriously b/c I really want to make a change.
It's just miserable in the meantime.
