A little practice will go a long way
You know that newborn swaddling can reduce the risk of sudden infant death syndrome (SIDS), and by now your wife may have told you of swaddling’s magical powers in reducing colic and calming even the fussiest screamer. But has anyone shown you how to actually do it?
Postpartum haze can make even the simplest tasks seem like rocket science—add a wiggling infant to the equation and it could be a deal breaker.
 
Here’s your simple guide to swaddling

1.With the receiving blanket open on a flat surface, fold down one corner. Then place baby in the center, with the folded edge at baby’s shoulders.
2.With baby’s right arm is over his chest, pull the left side of the blanket snugly across his body and tuck it smoothly around and under him, leaving his left arm out.
3. Pull up the bottom corner of the blanket and tuck it around baby’s left arm and behind his left shoulder.
4. Draw the right corner of the blanket across baby’s chest, tucking the corner behind his back to fit snugly.
And remember :
Always place swaddled baby on his back.
Do not swaddle beyond three months; this can effect motor development.
Do not swaddle baby in an overheated room; this increases the risk of SIDS.  Ideal room temperature for sleeping is 65–70 degrees.
Not all babies like their arms swaddled; notice your baby’s cues; adjust accordingly.
