I couldn’t have said this any better if I’d tried. My email and text replies can come slowly. Because people right in front of me - especially those in labour - come first.

Amazing

During pregnancy, fetal cells migrate out of the womb and into a mother’s heart, liver, lung, kidney, brain, and more. They could shape moms’ health for a lifetime, Katherine J. Wu reported in 2024:⁠ https://theatln.tc/W8aBhPp2
⁠
The presence of these cells, known as microchimerism, is thought to affect every person who has carried an embryo, even if briefly, and anyone who has ever inhabited a womb. The cross-generational transfers are bidirectional—as fetal cells cross the placenta into maternal tissues, a small number of maternal cells migrate into fetal tissues, where they can persist into adulthood. ⁠
⁠
Genetic swaps, then, might occur several times throughout a life. Some researchers believe that people may be miniature mosaics of many of their relatives, via chains of pregnancy: their older siblings, perhaps, or their maternal grandmother, or any aunts and uncles their grandmother might have conceived before their mother was born. “It’s like you carry your entire family inside of you,” Francisco Úbeda de Torres, an evolutionary biologist at the Royal Holloway University of London, told Wu.⁠
⁠
Some scientists have argued that cells so sparse and inconsistent couldn’t possibly have meaningful effects. Even among microchimerism researchers, hypotheses about what these cells do—if anything at all—remain “highly controversial,” Sing Sing Way, an immunologist and a pediatrician at Cincinnati Children’s Hospital, told Wu. But many experts contend that microchimeric cells aren’t just passive passengers. They are genetically distinct entities. And they might hold sway over many aspects of health: our susceptibility to infectious or autoimmune disease, the success of pregnancies, maybe even behavior. ⁠
⁠
If these cells turn out to be as important as some scientists believe they are, they might be one of the most underappreciated architects of human life, Wu writes.

Let’s talk about why a successful VBAC is more than just a single experience—it’s a game-changer for future births.

If you’ve had one VBAC, your chances of having another successful VBAC go way up—studies show success rates can reach 85–90+% with each subsequent VBAC. Your body has done it before, and it’s more likely to do it again. 🙌

But that’s not all. A prior successful VBAC can actually decrease your risk of uterine rupture in subsequent labors. After one successful VBAC, that risk can drop to as low as 0.2%—lower than the average risk quoted for someone attempting their first VBAC.

This is powerful information for anyone on their VBAC journey, and it's exactly why your birth experience matters not only for today, but for all the births that may come after.

Whether you’re preparing for your first VBAC or already celebrating one, know this: your body, your choices, and your birth story are building something bigger.

A widespread myth about infant sleep is - babies need to fall asleep alone for naps, bedtime and when they wake in the night - in order to build lifelong sleep health.

The exact opposite is true. When we accompany infants 0-3 years and children to sleep we build lifelong sleep health by:

🧠 Lending our adult brain so infants enter sleep in a rest and digest parasympathetic state

🧠 Create an association between sleep and a feeling of safety and comfort

🧠 Facilitate brain waves in sleep that are more restorative

🧠 Influence less night waking

🧠 Help them go to sleep faster

🧠 Influence their childhood, adolescent and adult sleep to be more consolidated, better quality, reduced insomnia

If we’ve been trying to get our baby to fall asleep alone or if we’ve been leaving them to fall asleep alone - and we see our baby is struggling with this - consider making a change. If we’re a new parent please know - your baby needs you and that’s simultaneously normal, expected and challenging.

Our presence makes all the difference in their developing brain between stress and nurture. It builds the brain towards resilience and builds sleep health.

When babies and children have sleep nurtured they grow up to sleep independently.

So so true. My beautiful best friend recently had her first baby post 40 and I was so excited to see her on the other side too.

"Recently, a friend texted me: Here we go, she said. It was a photo of her in a hospital gown.

Lovely and tired, she was in labor and I felt ever so vividly where she was. ⁣⁣⁣
⁣⁣⁣
I remembered myself in her place.

I remembered the childless girl who went into a labor and delivery ward scared and in pain and full of wonder and naivety and fear and excitement.

I remember being embarrassed when my water broke in a Hollywood-style fashion all over a cold hospital floor with wonderful strangers around me.

I remember the hours that followed.

There was so much unknown. ⁣⁣⁣
⁣⁣⁣
I remember the feeling of lightness when Sunday arrived and the heaviness in the days that followed when the visitors left and the hormones crashed and a wave of newness like nothing I’d ever known came over me. ⁣⁣⁣
⁣⁣⁣
In a way, when I saw my friend’s text, I missed the girl I was when I walked into the hospital that day. The one who lived in a tiny little apartment and took long runs and longer showers and lounged with coffee and slept in. I don’t always feel like I know her anymore. Glimpses of her, maybe. But not the full her. ⁣⁣⁣
⁣⁣⁣
In a way, I wanted to say to my friend: Live in those last few moments. Hug your husband. Cherish that time. ⁣⁣
⁣⁣⁣
But I didn’t. ⁣⁣⁣
⁣⁣⁣
I also knew that contractions hurt and it was hard (because it is) and being so close to the unknown is so uncomfortable yet so strangely spiritual. ⁣⁣⁣
I also wanted to say this: That the person she is becoming, the person she will become tonight, will awe the person she is right now.

I wanted to tell her that the little baby she was about to meet will introduce her to herself. ⁣
⁣⁣⁣
I wanted to tell her that the days that are about to follow will be hard—but that it would all be okay. Because the mess of it all is what makes it so beautiful.

(But in quiet moments she’ll always dream about lazy afternoons.)⁣
⁣⁣⁣
I didn’t though.

Instead I told her she was doing great.

I told her I’d be here if she needed me.

I told her I couldn’t wait to see her on the other side. 🤍"
