Baby Poo: A guide for every parent
Baby Poo: A guide for every parent

Bet you never thought you’d be so obsessed with human faeces, huh? All of a sudden, mothers need to know the colour, consistency and frequency of every poo – as if looking into that nappy will give us the answers to the universe. To be fair, it’s one of your only ways to tell if your baby is well fed and healthy, and seeing an off-putting bowel movement can send you into panic mode. Here’s what you need to know about poo:

 

Week 1

  • Colour and consistency

If your baby is eating normally and doesn’t seem sick, changes in the colour (even green or grey) and consistency of the stool is most likely normal. A newborn’s first stools (known as meconium) are a thick, sticky, tar-like substance, which will then transition into a grainy yellow or brown by day three or four. Formula-fed babies tend to have a slightly formed, yellow or tan coloured stool, while breast-fed babies often have a more liquid or creamy mustard-coloured bowel movement.

 

  • Frequency

Expect 6 to 8 stools a day. If the stool is very frequent, watery and green looking, chances are the baby has diarrhea. Diarrhea should clear up without treatment within 24 hours, but call your doctor if concerned. If accompanied by vomiting, call your GP immediately due to risk of dehydration. Constipated stools will be pebble-sized and firm, sometimes with bloody streaks. If you see blood, have your baby checked out by your baby health clinic professional or GP, to check out all possible causes. The frequency has nothing to do with constipation, as it does with adults. It’s normal for babies to grunt and strain during a normal, healthy bowel movement.

 

Weeks 3-4


Your baby might still have 6 to 8 bowel movements a day, but don’t be alarmed if the frequency diminishes or even disappears for a day here and there. More than frequency, the color and consistency will tell you if something is wrong. Babies are renowned for turning red, pulling faces, grunting and bicycling their legs with the strain of bowel movements. While this can cause alarm for new parents, it’s not necessarily constipation, which is characterized by pebble-sized, rock-hard stools. If you’re noticing green, frothy poo (arriving in an explosive manner!), it may be that your baby is suffering from lactose overload. This is often seen in babies who consume large amounts of breastmilk, due to their mother’s oversupply. The Ministry of Health suggests that changing to an ‘on demand’ breastfeeding routine may help.

 

After 12 weeks

 

Baby’s poo will continue vary in colour, consistency and frequency, though you will get to know what’s normal for your child. The next big change occurs once he or she begins eating solids at 4-6 months, when, unfortunately, the poo tends to become smellier.
