It is always difficult to keep your babies and children cool in the summer months in the UK or on holiday and it may seem like a good idea to cover the pram/buggy whilst they are sleeping with a blanket to sheild them from the sun, but experts warn that covering a pram can cause your baby to overheat – increasing the chance of sudden infant death syndrome (SIDS).
www.madeformums.com stated, a study found that the temperature inside a pram can reach 22C on a warm day. But when a thin cover was placed over the pram for 30 minutes, the heat rose dramatically to 34C. After an hour, the temperature was a sweltering 37C. "It gets extremely hot down in the pram, something like a thermos,” Svante Norgren, paediatrician at the Astrid Lindgren children's hospital in Stockholm, told the Svenska Dagbladet newspaper. "If a child gets too hot then the child may think that it is back in the womb, which is why breathing may stop,”
"Covering a pram or buggy with a blanket could lead to overheating, which increases the chance of SIDS," says Lucy McKeown of the Lullaby Trust. "Using a blanket would also create a barrier between parent and baby, which is also slightly risky: parents won’t be able to see if their baby is having difficulties, and they won’t be able to monitor their baby’s temperature easily (by feeling their tummy or back of their neck)." So could using a thinner material help? "Breathable and thin materials would be better, but not using any blanket at all would reduce the chance of overheating," says Lucy.
Instead, the charity recommends attaching a clip-on sunshade or parasol to a pram or buggy. "We also recommend all parents follow our recommendations for hot weather," adds Lucy, "which include light bedding and clothing for sleep, keeping a door or window open if it is safe to do so, and ensuring non-breastfed babies have sufficient fluids."
