Contrary to popular belief, babies are more acclimated to warm temperature. That said, during summer, babies need not be bundled like burritos, fitted with socks and mittens, and protected by a hat. Equally, since they cannot self-cool through sweating as efficiently as adults, they need to wear as little clothing as possible:

Cotton clothes- In the summer heat, babies should be dressed in as little as possible. Contrary to the belief that babies must be bundled 24/7, it is better if they are dressed in breathable clothes so as to allow the sweat to escape while also cooling them down.

Nappy- If it is really too hot, then dressing baby up in nothing but a nappy is also acceptable. They need to be exposed to stay cool—just make sure that baby does not get too cold in the process.

Cotton Wrap- Lastly, babies sleep better when they are bundled up. When it is time to sleep, wrapping baby in a thin, breathable cloth—wearing nothing but a nappy—is the best way to go.

Always protect your babies skin from the harsh sun, keeping them in the shade and away from the midday sun.
