When the weather is hot, your baby makes it sweltering! Keep yourself hydrated by drinking lots of cool water. Consider carrying a spray bottle of water (keep it in the fridge overnight so that it's nice and cold next day) to spritz you when you're too hot.
Opt for sleeveless clothing that is made of natural fabrics, such as linen and cotton, which will help keep the air circulating. If you want to keep some or all of your arms covered, wear short-sleeved jackets or cotton cardigans. Wear a sun hat and sunglasses, especially if you're in direct sunlight for any length of time.
Opt for flip-flops or low-heeled sandals to let your feet breathe-these can also be a good option if your feet are swollen.
