The smelly question: Is my baby’s poo normal?

With questions around colour, texture and smell, it’s one of the most talked about subjects amongst new parents, and Tommee Tippee are here to help: is your baby’s poo normal?

Baby poo appears in a whole range of surprising shades and forms, and can keep even the most experienced parent guessing. These simple tips should help demystify the nappy once and for all.

This is the most unusual and surprising poo, made up of meconium (everything mum ingested while baby was in the womb!). This poop is a dark green-black and very, very sticky – almost a tar-like consistency. This is normal and may last for a few days.


Following the meconium stage, the poo will become a lighter shade of green-black, and then yellow. It is often bright and the texture will become grainy (think wholegrain mustard!), and even loose, rather than sticky. Bonus: the smell is much sweeter at this stage!


Bottle-fed babies are likely to produce bulkier poo than those who are breast-fed, and the colour is often a pale yellow or yellow-brown. It will also possess a stronger smell. These small differences arise as it is more difficult for your baby to digest formula than breast milk.


Now comes the biggest change! With solid foods, your baby’s poo will become larger, thicker and, unfortunately, smellier – much more similar to an adult’s. The shade will also become more changeable, affected by different foods. At this stage, certain hard-to-digest foods may pass straight through, but this will change as your baby gets used to a variety of food types. Hint: those little black flecks are probably banana!


We’ve established that baby poo comes in all sorts of shapes, sizes, smells and colours – but there are some signs to watch out for:

  • Diarrhoea – can be a symptom of teething or an allergy, but always check with your doctor just in case.
  • Constipation – some babies just don’t have to go as much as others, but if yours is really struggling, run this past your doctor.
  • Blood – this is usually a symptom of constipation and can be remedied quite easily. Nevertheless, you should always consult your doctor to be on the safe side.
  • Green poo – normal in newborns, but could be a sign of infection in older babies.
  • Pale poo – a sign of jaundice, common in newborns. Speak with your doctor if this lasts longer than a couple of weeks.

If there is ever a time to wonder just how much your life has changed since parenthood, this might just be it!
