My lo (15mo) is in a an all in one pyjama (with feet) with most of the poppers done up and a blanket for comfort (not cover). It's 25 degrees inside with the windows open and i'm wondering if he should be in something else. He was in a long sleeved vest in a 1tog grobag til recently but i thought that was too hot and i think it'd be too cold in just a vest. What do other people dress their babies in in these temperatures?
