My little girl is nine months old and I'm really worried about the heat. She slept OK last night but all the room thermometers go red at about 22 degrees and I can't keep her room cool at the moment. I leave the blackout blind shut during the day to keep the sun out and leave the window open at night to try and let the air in. She's just in a nappy in her grobag (1.5 tog) at the moment - should I give up on the grobag? Is it worth try to get a fan to cool the room or am I just being neurotic?
