Three early signs a baby is hungry include rooting (turning head and opening mouth as if searching for the breast/bottle), bringing hands to mouth, and lip smacking or sucking motions, all indicating they are ready for a feed before they start crying, which is a late sign of hunger.
Watch for these signs that your baby is hungry, and then feed baby right away:
Early Hunger Cues
Look out for these gentle signals that your baby is ready to feed: Opening their mouth. Turning their head from side to side. Stirring or becoming more alert.
Signs your child may be hungry
Puts their hands to their mouth. Turns their head toward your breast or the bottle. Puckers, smacks, or licks lips.
Not all babies exhibit the same behaviors when they're ready to eat, but here are a few signals that typically indicate “feed me!” Excited. Arms waving, legs kicking.
The 7 key danger signs for newborns, often highlighted by organizations like the WHO, are not feeding well, convulsions, fast breathing, severe chest indrawing, lethargy/unconsciousness (movement only when stimulated), high or low temperature, and jaundice (yellow skin/soles) or signs of local infection like an infected umbilical stump, requiring immediate medical attention.
Signs of overfeeding a baby include frequent spitting up/vomiting, fussiness, gassiness, a tight belly, and changes in stool (loose, green, frothy, or explosive). While babies often know when they're full (turning away, falling asleep), signs of overfeeding often involve discomfort and digestive issues, sometimes with rapid weight gain or a very full, hard tummy, especially if fed past fullness cues.
The 2-hour rule for babies means they shouldn't stay in a car seat (or travel system seat) for more than two hours at a time, whether in or out of the car, because the semi-upright position can strain their developing spine and restrict their breathing, increasing the risk of low oxygen levels, especially for newborns and preemies. For long journeys, parents should take breaks every two hours to take the baby out, allow them to lie flat for a while, stretch, and feed, ensuring they get proper head/neck support and circulation.
Why do babies make an O shape with their mouths? Babies often make an "O" shape with their mouths when they're feeling content and relaxed.
You can start teaching your baby simple sign language around 6 to 7 months old – though it may take a couple of months before they start signing back! Some basic signs to start with include the gestures for drink, more, please, thank you, and help.
As their stomach fills up, you may notice a change: the strength of their suck decreases, swallowing becomes less frequent, and you might feel their tongue lightly tickling the tip of your nipple. This is a sign that they are shifting from active eating to non-nutritive sucking.
Signs that your baby is full
Your baby has decided not to drink any more milk for now. This is how your baby learns what being full feels like and so is unlikely to overfeed.
While some newborns drift off to sleep for short periods even when hungry, this sleep is usually light, restless, and fragmented. The body's hunger signals keep nudging them awake, making it difficult to stay asleep for long stretches–their body needs nourishment.
But Scott cites weight gain as the best indicator of whether baby's getting enough to eat. (Your pediatrician will check this at each of baby's well visits.) Additionally, pay attention to baby's hunger cues, such as rooting, smacking their lips, bringing their hands to their mouth and becoming more alert.
The "4-4-4 rule" for breast milk is a simple storage guideline: fresh milk is good for 4 hours at room temperature (up to 77°F/25°C), for 4 days in the refrigerator (39°F/4°C or colder), and up to 4-6 months (or longer) in a standard freezer (0°F/-18°C). It's a handy mnemonic, though some organizations like the CDC recommend up to 6 months in the freezer and the AAP up to 9 months, with deeper freezers offering even longer storage.
Watch for signs that your baby is full (slowing down, spitting out the bottle or unlatching from breast, closing the mouth, turning away from the breast or bottle) and stop the feeding when these signs appear. As babies grow, they begin to eat more at each feeding and can go longer between feedings.
The first three months with your baby often seem the hardest. Sleep-deprived parents can feel overwhelmed, but that is normal and you will quickly learn how to read your baby's cues and personality. Don't worry about “spoiling” your baby at this stage.
Why Does SIDS Peak at 2-4 Months? The widely accepted explanation for the SIDS peak has to do with the timeline of brain development. “Up to 4 months old, the part of the brain that controls breathing and wakefulness is under a lot of development,” Juliet explains.
Hold your baby until they're in a deeper sleep. Babies start in 'active sleep' (with faster, uneven breathing) and move into a deeper sleep after about 20 minutes. That's a good time to transfer them into their sleeping place. Many babies don't like being put down into a cot.
No bowel movement in the first 48 hours. A rectal temperature over 100.4 degrees F (38 degrees C) or less than 97.5 degrees F (36.5 degrees C). A rapid breathing rate over 60 per minute, or a blue coloring that does not go away. Newborns normally have irregular respirations, so you need to count for a full minute.
Beyond the cuteness explosion you can expect when Baby starts smiling around 6 to 8 weeks, it's also an exciting time for their development. Baby's vision and facial recognition is improving, and they're outgrowing their early reflexes. They're also beginning to express feelings, such as excitement or contentment.
