My 8 month old is really unsettled in the heat and it doesn't matter what a do to try and cool me house down nothing seems to work. My bedroom is the hottest room in the house and even when it cools down on a night time my bedroom is still 23 degrees with the windows open can the little one just sleep in a vest without a blanket on with the windows open as his arms and legs normally feel really cool when he's asleep I'm unsure what his chest and that feel like
