6. You don't need to change a wet diaper immediately. "Today's disposables wick away moisture, so your baby will stay dry until the diaper is close to overflowing," Shu says. (Not that you should let it get this full; this can set the stage for a nasty rash, especially if you're using cloth diapers.) Use discretion with wet diapers at night, too: Changing your baby can be stimulating and make it difficult for him to get back to sleep. A poopy diaper is another matter, though: Change promptly.
7. Your job is to go with the flow. Most newborns have absolutely no eating or sleeping schedules, and trying to impose them will only frustrate you both. But with time, your baby will naturally fall into a routine. "Babies typically establish a sleep routine between the age of 1 and 4 months," Shu says. "Eating is more predictable: Newborns fall into an eating pattern pretty soon after birth."
8. Crying is normal. It's your baby's only way of expressing himself. This is small comfort at 3 a.m., of course. To soothe your baby, try pediatrician Harvey Karp's "5 S's":
• Swaddle your baby tightly.
• Hold him on his side or stomach.
• Make shushing noises in his ear.
• Make them as loud as the crying.
• Swing him, either in your arms or a swing.
• Let your baby suck. A pacifier, bottle or breast will do.
If this doesn't work and you become concerned, don't be shy about calling your pediatrician. "It's typical for infants to cry for a total of two to three hours over the course of a day," Shu explains. (To make matters even worse, it often peaks around your dinnertime.) "But if there's a change in your baby's crying pattern and you're worried, err on the side of caution and seek help. Parents' hunches are often correct."
Also keep in mind that babies do outgrow their fussiness. "It usually begins about two weeks after birth and peaks by the age of 6 weeks," Shu explains. "And it's usually gone by 3 to 4 months."
9. It's OK to walk away. If your baby is screaming inconsolably and you need a break, take 10 seconds or 10 minutes—whatever is required—to compose yourself. Just be sure your baby is safe before doing so. "Babies don't die from being in a crib or bassinet when you have to walk away," Shu says. "They die when parents get so overworked that they shake them."
10. You don't need to entertain your baby every minute. Whether they're looking out the window or staring at a light, infants are continually learning. Give your baby the space to discover his world—and don't feel that you need to bombard him with stimulation; this may only make him fussy. "Any time you spend engaged with your baby is quality time," Shu explains. "Even if you're doing something as mundane as going to the grocery store, talk to him and make eye contact as you shop."
