Dd is 6 months. She woke at 3 ish this morning with freezing arms and hands. The rest of her felt warm enough. She was in a pyjama/babygro thing and a 2.5 tog sleeping bag. I put an extra layer on her, a long sleeved top when I took her back to bed. This morning she was like a little icicle when she woke and took a good few minutes to warm up. The temperature in our room was 12 degrees when I checked (around 7). It's supposed to be a couple of degrees colder tonight and I'm not sure what to dress her in. Any advice?
