    Why Holding Your Baby Skin-to-Skin Is So Powerful

    From regulating body temperature to promoting bonding, the benefits of skin-to-skin are profound!

    Your baby is rounding the corner on their second month of life—and those sleepy newborn days may feel like a distant memory. By now, your baby is really waking up to—and is fascinated by—the amazing lights, colours, and sounds all around.

    You’re really getting a glimpse of what playtime will look like as your baby gets older. There’s still lots of watching everyone coming and going, but also lots more interest in active play. As a result, you’ll notice new skills, like batting at toys, holding the head for longer periods, and having fun grasping small objects, like a rattle.

    Feeding Your 7-Week-Old Baby

    For a tiny little nugget, your baby may have quite the appetite! Generally, babies gain 0.7 to 0.9 kilograms of body weight per month. Regular feeding—every couple of hours—is still important to keep your baby fueled.

    Your 7-Week-Old Baby’s Development

    All these feedings give energy for tummy time, but also nourish very active brain growth. Whether your baby consumes breast milk, formula, or a combination of the two, the vitamins, minerals, and nutrients they digest are essential for building the brain’s important pathways. Amazingly, your baby’s brain is adding 250,000 to 500,000 cells every second!

    7-Week-Old Baby Sleep

    Your 7-week-old baby should be sleeping really well (in SNOO babies often have 5, 6, or even 7-hour stretches of continuous sleep). And all that rest is helping them make the most of their awake periods. In early weeks, babies just wake up and quietly look around, but now your baby spends longer periods actively alert and playful. By watching them track moving objects with their eyes and batting at things with their hands you can see that the senses are starting to come together in ways that build the foundation for major motor skills to come!

    As much fun as you two may be having together, it’s important to schedule some mellow downtime. Ideas include taking walks, singing lullabies, doing little massages, and rocking in a rocking chair.

    7 Week-Old Baby Sleep Regressions

    Some parents notice a sleep regression as their little one approaches 3 months. Regressions are marked by early-morning or middle-of-the-night wakeups and trouble falling asleep that seemingly sneaks up on you (and your baby) out of the blue. When it comes to sleep regressions, the best cure is prevention. I advise continuing to use the 5 S’s (or SNOO), to help soothe your baby to sleep. You might want to consider using a dream feed to top your baby off before bed. And be sure to get outside early in the day—this can help get your baby’s internal clock back on track!

    How to Spot a Fever

    Fevers aren’t pleasant at any age. For infants younger than 12 weeks, however, any temperature above the normal range is cause to ring up your paediatrician.

    • Before 6 months of age, the most reliable ways to check for fever are with rectal, forehead, or under-arm thermometers (not ear thermometers). A fever is a temperature above 38.0° C.
    • As well as feeling hot to the touch, symptoms associated with fever include irritability (more than usual and not just at the witching hour), lethargy (very little good alert time, sleepiness to where baby is just not eating what you would expect).
    • Viral infections are the most common cause of fevers, but bacterial infections in the babies are common, too, and can worsen quickly. 
    • If your infant younger than 3 months has a fever, do not treat the fever with medication before seeing a paediatrician. Call to discuss your baby’s condition right away…don’t wait for the morning. 

    Disclaimer: The information on our site is NOT medical advice for any specific person or condition. It is only meant as general information. If you have any medical questions and concerns about your child or yourself, please contact your health provider. Breastmilk is the best source of nutrition for babies. It is important that, in preparation for and during breastfeeding, mothers eat a healthy, balanced diet. Combined breast- and bottle-feeding in the first weeks of life may reduce the supply of a mother's breastmilk and reversing the decision not to breastfeed is difficult. If you do decide to use infant formula, you should follow instructions carefully.
