It's an unpopular parenting choice, but I had to start letting my daughter cry at night around that age. She was way too dependent on me to fall asleep and stay asleep so when I would put her down at night she would wake up all the time. She is almost 14 months now but she sleeps through the night and puts herself to sleep.

I've always just let mine sleep whenever he's tired. Til this week that is, but he's nearly 2.
