How to Calm a Baby 0-3 months: The 5 S's
Step 1: Swaddle
Wrap your baby in a swaddle. It is best to practice wrapping baby in a swaddle when she is calm to get her used to the swaddle. But if she is fussy continue wrapping in the swaddle even if she appears to not like it. Make sure arms and legs are wrapped snug in the swaddle.
Step 1a: Wrap or sling
During the day, wear your baby around in a wrap or sling. The snug, tight, close, swaying motion of a wrap reminds your little one of the uterus and makes him feel right at home and calm. A sling also teaches your baby the difference between night and day.
Step 1b: Sleep Sack
During the night, we would put our son in a sleep sack when he was ready for bed. He was the most secure in the sleep sack and had a harder time wriggling out of them.
Step 2: Side/Stomach Position
Once your baby is nicely swaddled, roll him onto his stomach or side in your lap. This position will relieve any pressure or gas that he may be feeling in his stomach. Never put a baby to sleep in this position.
Step 3: Shush
Next, add a loud shushing sound. Moms tend to do a quiet shushing sound but the louder the better. It was noisy in the uterus. Download some white noise, a high pitched hair dryer sound, or white noise and turn it up. Turn on a sound machine for the evening.
Step 4: Swing
Then add in swinging or gently rocking to replicate the movements of the womb. Whether you use your arms to jiggle your baby, a wrap, an exercise ball to bounce, or a swing/bouncer, the gentle motions will calm your child down in no time.
Step 5: Suck
Finally, plop a pacifier or teether into your baby's mouth to add the cherry on top!
