Why Are Babies’ Digestive Systems So Utterly Useless?

Advertisements

I can’t be the only parent who has looked at their beloved baby, covered in vomit at 4am after waking up crying because of trapped wind, and wondered… Why are babies born with such completely useless digestive systems? Are we the only mammal this bad at eating and pooping? Do baby monkeys get colic? And when will my child finally be able to get through a day without continuously leaking milk curds from the sides of his mouth like a pint-sized Vesuvius?

Reflux and Spitting Up

In young babies, the lower oesophageal sphincter, which separates the stomach from the oesophagus, is weak and immature, and consequently does a terrible job of keeping the contents of baby’s stomach where they’re supposed to be.

Additionally, it can take a while before baby’s stomach gets into the swing of it’s normal squeezing pattern, meaning that milk may sit in the stomach longer than normal.

The good news is that reflux should subside in around four to twelve months!

Painful Wind

Babies are rubbish at eating properly, so they take in a lot of air when feeding. Then because they just lie around like lazy little beached porpoises all day, they can’t easily eliminate the gas via the normal route of burps and farts.

Tiny bubbles of gas then cause pressure and stomach pain. And that causes very grumpy babies. Here’s the irony: crying babies also often take in excess air. Which causes gassy pain. Which causes more crying. You see where I’m going with this. It’s kind of a vicious cycle.

In theory, this should improve around 3 – 4 months of age, or when the baby starts rolling on his own, as this helps to get the gas out.

Tummy Upsets

Humans are supposed to have a (delightfully named) “digestive mucosal lining” or layer of mucous, which protects their digestive tract from microbes and other contaminants in food. In babies, this layer is thin and does a bad job at protecting their gastrointestinal tract from infection.

Weaning

Current recommendations are to avoid weaning babies until they are about six months old. Why? I found it really interesting to read about this:

  • Babies can’t produce digestive enzymes to digest starches until they’re six months old.
  • They don’t produce enough enzymes to digest complex carbohydrates until nearly seven months.
  • Their bile and lipase for digesting fats don’t reach full levels until six months.
  • Until about six months, babies’ guts allow large molecules to pass directly into the bloodstream. This is to allow antibodies from mum’s breastmilk to pass into baby’s blood. But it also allows larger molecules from solid food through, which could create a risk of infection or allergy.

Little Man has had a bad tummy ever since we got him home from hospital. I think a lot of it is due to him taking in air when he eats, because when he was in intensive care and then on the ward with me, we fed him through a naso-gastric tube, and he didn’t vomit as much or have anything like as much trouble with his tummy. Can’t wait until it all settles down, but it doesnt seem like it will be happening any time soon…

“Mummy, What Did You Do During the Pandemic?”

“Mummy, what did you do during the pandemic?”

“Well, darling, mostly I sat around the house wiping your vomit off things.”

It’s been three weeks now and I’ve left the house once for a walk and once to take Little Man to the doctor’s for his second set of vaccinations. It’s not really how I envisaged my maternity leave going. After two months, I’d just got to the point where taking Little Man out no longer felt like a huge undertaking, and I could predict how much time I would need to get us ready before leaving the house. I was just starting to think of doing some more adventurous trips out with him on my own, when coronavirus really hit and we had to stay in the house.

It’s hard not to be a bit gutted when I think of all the plans we had for maternity leave which probably won’t happen now. We were planning to take him for a couple of weeks in Ireland, drive down to Devon, we had family planning to visit from Japan in the summer, I was hoping to arrange some kind of ‘welcome to the world’ party for him… The list of cancellations goes on.

Equally, we have to get through this by staying positive and there are some positives. His dad is working from home which means he gets to spend so much more time with us, and that’s lovely for everyone (although he may not agree when he’s on a conference call and Little Man is kicking off downstairs). Plus, financially things aren’t so tight as expected with my maternity pay reduction, because we’re not going out and spending money.

Sometimes it feels a bit useless to be sat indoors, so I have to keep reminding myself that we’re at least doing our bit to try to avoid spreading this horrible virus around. We’re so grateful to all the keyworkers who make it possible for us to stay at home, from the delivery men who bring our shopping, to the medical staff on the front line who probably would like nothing more than to be sat at home with their kids every day, wiping vomit off things.

Top Tips for the Coronavirus Outbreak: #002 Vomit Explosion PSA

Another Public Service Announcement from the Little Man at this difficult time… Not all vomit is coronavirus vomit.

He is honestly such a comity baby, it is unreal! I had expected my baby to throw up to some extent, but he really does seem to have a very sensitive tummy because the vomiting is more or less constant – we even took him to the doctor’s and hospital when he was smaller to get him checked over because of it (at the time he was routinely projectile vomiting as well, which has fortunately reduced in frequency!). They checked him out for various things including cow’s milk protein allergy, and concluded all was well… He’s just very comity.

It’s amazing how being a parent changes your hygiene standards. Before, if got vomit on my clothes, I would of course immediately go change. But now, I know that the fresh clothes will just get covered in sick within about ten minutes anyway, so I have to admit I take a much more relaxed approach!
