Summer is here, and so is your desire to get outside and enjoy it! But as a new mom, you must be concerned about your baby’s safety in the heat, and for good reason. Even small amounts of water loss can affect infants, and dehydration can become serious quickly. That’s why knowing how to keep your baby cool during hot weather is essential. A simple but important step is to keep your little one out of direct sunlight. Learning these strategies will help ensure your newborn stays comfortable, safe, and happy as the temperatures rise.

To enjoy the season without worry, check out these expert tips for keeping baby cool in summer.

How to Keep a Newborn Cool in Summer?

Here are some smart ways to help your baby beat the heat. And the best part? You can try all of these ways to keep baby cool in summer without breaking a sweat!

1. Stay Out of Direct Sunlight

You should always follow one mantra: “Keep your baby out of direct sunlight.” Babies are extremely sensitive to heat, and since their immune system is in the development stage, they are not capable of regulating their core body temperature (1). So, keep your baby covered whenever you go out. One of the best ways to keep your baby out of direct sunlight when you head out of home is a baby stroller. Invest in a stroller that comes with an adjustable sun canopy or shade to give the best protection to your little one. Also, make sure of some important features, like safety standards, age suitability, seat compatibility, etc.

2. Dress Your Baby Smartly

When it’s hot outside, loose-fitting, lightweight cotton garments are your best bet as they absorb perspiration better than synthetic fabrics and are gentler to the skin (2). You can even opt for a light onesie during the summer months. Ditch the layered (however cute they may be) outfits as your baby’s comfort is your topmost priority. Remember this good rule of thumb: “Dress your little one the way you’re dressed.” Now, you wouldn’t be wearing extra layers of clothing during the summers, would you?

3. Provide Good Ventilation

One major issue with the summer is the stuffy feeling and humidity. This combination is a sure-shot way to make your baby very cranky! To avoid this, ensure your home is well-ventilated. Fans help circulate air, so they might be more effective than an air conditioner in getting rid of the stuffiness (3).

4. Ensure Your Little One Is Hydrated at All Times

Even if you don’t see beads of sweat rolling off your infant’s forehead, she can be losing precious fluids in the hot weather. Staying hydrated is the key to keeping cool, particularly during the year’s warmest months. And this applies to you, too, if you’re breastfeeding your little one. If bottle-feeding or weaning, make sure your baby drinks plenty of cooled boiled water even at night (4). If your baby has transitioned to using a sipper cup, you can have more than one spout cup or sippy cup and place them at different locations in the house accessible to your baby to encourage her to drink more fluids and stay hydrated.

Pro tip: Do not give your baby anything other than water, like juice, in a sipper as it can lead to tooth decay.

5. Apply Baby-Safe Sunscreen

Before heading out with your baby, you check if all things are in place. Stroller-check, full-sleeve cotton dress-check, summer cap-check! Sunscreen-check? After your little one turns six months old, make sure to apply a suitable amount of sunscreen to your baby’s skin. A good-quality sunscreen will give your baby the sun protection she needs. Why? Because babies have delicate skin that burns easily! Reapply the sunscreen every few hours, as it may be effective only for a couple of hours (5).

When buying sunscreen for your baby, look for active features, like a mineral base, either with zinc oxide or titanium oxide, as these don’t require many chemicals to protect the skin. Also, consider sun protection factor (SPF) with a minimum from 15 to 30.

6. Use a Summer-Friendly Baby Carrier

Your body heat and the baby carrier’s enclosed space can make your little one hot and bothered within minutes. Choose a carrier made from lightweight fabric rather than a heavy fabric like denim. If your baby’s face starts to look flushed, get her out of the carrier at once.

7. Get a Wide-Brimmed Hat

For the short amounts of time that your baby will be playing outside in your garden or even balcony, keep her head protected with a sun hat. Get one with a broad brim to keep the sun off her face. A hat with strings will ensure it stays put and that your baby doesn’t fidget and toss it away. Also, make sure that the hat is made of breathable and non-irritable material so that your baby’s head doesn’t get overheated.

8. Time Outdoor Activities Wisely

The worst time for your baby (and anyone, for that matter) to be outside is between 10 a.m. and 4 p.m. (6). That’s when the sun does the most damage to the skin. To be on the safer side, plan outdoor activities prior to or after this timeframe. This has got to be the simplest way to protect your baby from getting heatstroke or severely dehydrated.

9. Apply Talcum Powder

This is an essential part of your baby’s skincare routine during summer. The mild fragrance of talcum powder can add oodles of freshness to your little one. Talcum powder refreshes and protects your little one’s skin, leaving it soft, supple, and cool without clogging the pores. While applying the powder, keep the powder away from your little one so that she doesn’t accidentally inhale any of it.

10. Get an Inflatable Pool

This is one of the best ways of keeping baby cool in summer. Most babies love splashing around in the water, especially during the summer! Get your baby an inflatable tub and let her enjoy playing in the water. You can get her some bath toys, too, so that she has a gala time in the tub! A tub works better than a sponge bath on a very hot day.

11. Choose Breathable Car Seat Covers

Car seats can get very hot, especially when left in the sun. Thick or padded covers can trap heat, making your baby uncomfortable or even causing overheating. Instead, use breathable covers made of mesh or lightweight cotton, which allow air to flow and help keep your baby cool. Always check that the seat and cover feel cool before putting your baby in.

12. Use Cooling Accessories

During hot weather, small accessories can help your baby stay comfortable. Lightweight muslin wraps, stroller fans, or breathable pads allow air to circulate and prevent your baby from getting too warm. Always supervise your baby when using these items, and make sure nothing blocks airflow or creates a safety risk.

FAQs

1. Can I use a cooling gel pad or mattress for my baby during summer?

While cooling gel pads or mattresses might seem like a good idea, they are not recommended for babies. These products can become too cold and may cause discomfort or even hypothermia in infants. Instead, opt for breathable, lightweight bedding and ensure the room is well-ventilated or air-conditioned.

2. Should I avoid using a stroller fan for my baby?

Stroller fans can be helpful to keep your baby cool, but they should be used with caution. Ensure the fan is securely attached and positioned at a safe distance to prevent little fingers from reaching it. Also, avoid pointing the fan directly at your baby’s face to prevent dryness or discomfort. Opt for a gentle breeze instead.

3. How can I tell if my baby is too hot?

Signs of overheating include flushed or red skin, sweating, rapid breathing, restlessness, or unusual fussiness. If you notice these, move your baby to a cooler area, remove layers, and offer fluids if age-appropriate.

During summer, it’s not very easy to beat the heat, especially when you’re outside. And with a baby on board, you’ll want to take added precautions while spending time under the sun. But that doesn’t mean you can’t enjoy the warm weather while it’s here. Follow these tips for summer safety for baby, and it will all be smooth sailing, even on the hottest day!
