Waking up in the middle of the night is the most common concern among parents of newborns, who often find themselves sleep-deprived and stressed-out when they repeatedly wake up to soothe and cradle their baby. A new study from Temple psychology professor Marsha Weinraub found that the majority of these sleepless infants were boys, tended to score higher on an assessment of difficult temperament which identified traits such as irritability and distractibility, and were likely to be breastfed.

Now, the dilemma is: Should you let your baby "cry it out" when he wakes up at night? Or should you rush to coddle your crying little one?

Weinraub believes that a majority infants are best left to self-soothe and fall back to sleep on their own. "When mothers tune in to these night time awakenings and/or if a baby is in the habit of falling asleep during breastfeeding, then he or she may not be learning to how to self-soothe, something that is critical for regular sleep," she says. "The best advice is to put infants to bed at a regular time every night, allow them to fall asleep on their own and resist the urge to respond right away to awakenings."

So what's your approach? Do you let your little one cry himself back to sleep or do you tend to him without fail? Take the poll now!
