West London is enjoying some long-awaited sunshine this week, with Tuesday (July 19) easily the hottest day of the year so far.
However, while this has been something to celebrate for many of us, parents with babies or young children may be having a hard time getting them to sleep in the stifling heat.
Signs over overheating include youngsters becoming restless and unable to sleep.
Babies are at risk of Sudden Infant Death Syndrome if they severely overheat, so check if they are sweating on their head or neck or if they have a redder face than usual. Rashes or rapid breathing are signs of overheating.
So check out these 14 tips on how to keep your children comfortable at night so everyone can get a good night's rest.
If you don't have young children then some of these tips will be helpful for everyone, but don't forget to check out our separate guide for adults struggling to sleep too.
1. Appropriate clothing
If the room temperature climbs to 25C or hotter during the night then just a nappy and thin cotton vest is likely to be enough for your baby.
Temperatures of around 23C may require a shortie baby grow or shorts and T-shirt pyjamas perhaps with socks or just a nappy and a one-tog sleep sack.
For very young babies who do not use bedding, suitable clothing for the room temperature is fine so that no covering is necessary.
2. Keep it breezy
Open windows on the same floor during the day so air can circulate and pull curtains two thirds of the way across to block out hot sun but still allow the air in.
A good tip is to open the loft hatch to allow heat to rise up and escape through the roof.
4. Use the right bedding
Cotton bed sheets are good and waterproof mattresses should be avoided as they hold heat.
5. Try a refreshing bath
Bathing your baby in lukewarm or slightly cooler water may be refreshing and relieve clamminess. Make sure the bath is brief so baby does not get chilly.
6. Use a room thermometer
This means you know exactly what temperature you are dealing with and stops you guessing the right course of action.
7. Ice ice baby
Placing large (one litre or larger) bottles of frozen water in the child's room can cool the air as they melt overnight.

8. Give electric fans a helping hand
The ice bottles can also be used with an electric fan to stop them simply blowing hot air around. Place either a large bowl of ice or the bottles in front of the fan to cool the air.
9. Keep baby calm
A calm baby will remain cooler than a frustrated baby so try to maintain a calming bedtime routine and offer reassurance and comfort if they are agitated. A cool flannel or cold compress can be dabbed gentle onto their skin to help calmness and cooling.
10. Keep cold water to hand
Babies and young children may need to drink more than usual so put some bottles in the fridge for us at night time. Breastfed babies will stay hydrated on breastmilk.
11. Consider moving rooms
If you cannot keep your baby cool in one room, consider moving them to a cooler room temporarily.
12. Set them up for the whole night
Remember, no matter how hot it is at bedtime, the temperature will drop in the night so don't put your baby in the cot in just a nappy if it will drop below 25 degrees in the night. A temperature check when you go to bed is a good plan to see if any adjustments need to be made.
13. Accurately check baby's temperature
Hands and feet do get colder than the rest of the body so it is natural for these to feel a little colder to the touch. If you are unsure about your baby's temperature, feel the back of his neck or use a thermometer.
14. Put yourself in their shoes
Babies will be comfortable dressed for temperatures as you would dress yourself. So ask yourself how hot it feels and what you would be comfortable in when you are considering how to dress you baby.
Just remember, you can pull the covers over you but baby cannot, so imagine you are going to bed without any bed covers.
