Swaddling is believed to create a tight, warm environment similar to the womb. Even snugly wrapping your little tyke in a blanket and holding them close to your chest should help quickly calm them down. Get them warm and snug and start rocking. You can lay the baby on their side after swaddling. It better mimics the feeling of the womb and calms them faster. Just be sure to maintain constant supervision if you place the baby on their side. A pacifier or your finger is perfect. Sucking actually steadies a baby's heart rate, relaxes their stomach, and calms flailing limbs. This might be the ticket to a quiet, contented infant. If your baby is crying while struggling to fall asleep, you can remind them that you’re there with gentle touch. Lightly pat the baby’s back or rub gentle circles between their shoulder blades. You could even hold their tiny hand in your own. Any of these option can help soothe a baby enough to stop crying. Walk at a slow steady speed. Babies love rhythmic motion, and the lack of light will slowly make them sleepy. If you can, go outdoors—the change to fresh air may help them calm down. Gentle, calming movements are all that matters. Babies love to be touched, so slow, consistent massaging might slow them down and quiet their lungs. Play some peek-a-boo. Lie them on their back and rotate their feet like they were riding a bike. Make silly faces and talk to the child. Just being a distracting, stimulating influence may be enough to get them to stop crying. Babies need to be entertained, so entertain them! If you're out of options, it is time to look for help.

There is no reason to fear anything—but you should verify your specific situation with a professional.  If the crying is high-pitched, random, and the baby seems tense, they may have colic, a crying disorder. Luckily, colic tends to go away by the time your baby is 12-14 weeks old. Note when a baby cries to find patterns—right before a nap, after waking up, after eating certain foods, etc. Pay attention to your baby's signals to prevent future outbursts. Baby's crying usually peaks around 6 weeks, but it eases off afterward.

Summary:
Swaddle them in a warm blanket. Give them something to suck on. Pat the baby’s back. Walk around slowly in a dark area of the house. Gently massage your baby's feet, hands, and stomach. Play with your child to engage them. Call a hotline specifically for parents struggling with fussy babies. Call your pediatrician if the baby is still crying after you've checked the obvious causes.
