When the weather heats up, your baby’s feeding patterns might shift a little and that’s completely normal.
In hot weather, some babies feed for shorter bursts but more often, while others may seem less interested in longer daytime feeds. Breast milk naturally adapts in warmer temperatures, with a higher water content to help keep your baby hydrated. It can feel a bit unsettling but try to follow your baby’s cues. Remember to drink plenty yourself to stay hydrated.
If your baby is over six months, you can offer water-rich foods such as watermelon, cucumber or strawberries. Breast milk ice lollies can also be a handy way to keep them cool.
If you’re out and about, aim for a shaded, cooler spot for feeding. A fan or air-conditioned room can help, but avoid directing a fan straight onto your baby. Try to stay out of direct sun, particularly between 11am and 3pm, use shade like a parasol, and apply sunscreen of at least SPF30.
If you’re expressing, carry on as usual. You might notice your milk looks slightly more watery in the heat - that’s normal.
For formula-fed babies, they may take a little less at each feed but want feeds more often. If your baby is under six months, you may need to offer small sips of cooled, boiled water in hot weather, as formula doesn’t contain as much water as breast milk. These should be small amounts and not replace feeds. Keep an eye on wet nappies – around 4 to 6 in 24 hours is a good sign they’re well hydrated.
If you’re combination feeding, continue offering the breast more in response to your baby’s cues.
