Finding a suitable baby sleeping bag for the warm summer can be tricky. Apart from being comfortable, it must be lightweight and breathable enough so that our little one doesn’t overheat when they sleep, which can lead to a heat rash. The 0.5tog sleeping bag is an excellent solution because it’s specially designed to be worn in hot temperatures. So, what are the best 0.5tog baby sleeping bags in the UK right now?
What temperature is a 0.5 tog sleeping bag?
Baby sleeping bags come in different TOG ratings. The 0.5tog is the lowest Tog rating available for a sleeping bag, and according to the NHS, it’s suitable for use in hot weather and warm room temperature between 24-27C. Keep in mind that these sleeping bags aren’t suitable to use in colder months.
What happens if a baby overheats while sleeping?
According to the NHS, babies can experience overheating from excessive clothing or bedding, especially in a hot temperature room, and it can lead to the risk of SIDS. Apart from that, overheating in babies can also cause heat rash, heat stroke and dehydration.
