How Baby Poo Changes When Starting Solids

Let’s chat about baby poo. It smells, it’s messy and it happens all the time! From the moment your baby is born, or sometimes before, they poo. Hopefully it’s within their nappy, but sometimes it leaks out and you’re faced with a poonami! Baby poo is ever changing and this is something which surprises most new parents. Today we’re going to explain the changes you will see in your baby’s poop, with a focus on what it looks and smells like when they start eating solids.

What Should Baby Poo Look Like?

Poo changes over time. I know that’s a weird thing to say, but if you think about your own poo, you’ll know it’s true. The things we eat affect the colour, texture and size of our own poo. The same goes for our babies. A breastfed baby has different poop from a formula fed one. Colours can vary from yellow to green to brown. Black is the colour of the first poo, but if you see it at any other time, call your doctor immediately!

Regarding poo frequency, this varies widely. For some babies, once an hour or at every feeding is normal. For others, they get by on one per week. If you’re in any doubt about whether their poo is normal, chat with your midwife, Plunket nurse or GP.

Texture wise, a milk-fed baby should have relatively liquid poos, about the same texture as toothpaste. This changes though when they start solids…

How Baby Poo Changes As Solids Are Introduced

When you start introducing solids to your baby, expect to be amazed at how quickly their poop changes. These changes can be in frequency of bowel movements, colour of poo, smell, texture, size and consistency.

You can also expect to start seeing technicolour poo, with what your baby eats being seen in their poo! Some foods pass through undigested, and this is perfectly normal so don’t worry. Other foods are digested, resulting in thicker brown poos.

Sometimes baby poo can show that your little one reacts to certain foods, or as an allergy to them. If any of these signs appear, you’re best to stop that food until you’ve received medical advice.

  • Vomiting
  • Reflux
  • Diarrhoea
  • Nappy rash
  • Eczema
  • Slow weight gain

Diarrhoea can be a common sign when starting solids, caused by high fibre foods, but you are best to seek advice on this if it does happen. Constipation is also very common, caused by your baby not getting enough milk or fluid as they’re filling up on solids. Make sure you keep their fluid level up, because a constipated baby is no fun!

How Does This Affect Cloth Nappies?

If your baby has been breastfed, you may have got away without having to do much in terms of dealing with poo on nappies, simply rinsing in the washing machine and washing as usual.

But with the change in texture and consistency of poo after starting solids, you’ll find you have a lot more ‘solids’ to remove from the nappy as well! Some people like to have a dedicated ‘poo scraper’ to remove the worst of it. Toilet paper also works in the same way or you can purchase nappy sprayers which attach to the plumbing in the toilet. Some like to hold the nappy or liner under the flush of the toilet to rinse or you can rinse in the laundry sink afterwards. Whatever method you use, the more you can remove before the nappies go through the washing machine, the better!
