Should i let my two to four month old baby sleep alone?

Yes: If a baby learns how to start sleep alone, he/she will be able to go back to sleep after waking in the night. Your baby is 4 times more likely to develop a sleep problem that lasts up to three years if you rock or feed a baby to sleep. Babies over ten pounds don't need to feed in the night, yet will expect a bottle if they fall asleep eating.

Yes: Speak to your pediatrician about sleep positions for your baby. Make sure the baby has a proper crib and have a baby monitor so you can hear room sounds.
