Can I ask a really stupid question - what do you cover them with at night at this time of year? Blankets? Sheets? How many layers?
Ds2 (14mo) is kicking up the most awful fuss about being put into his grobag atm (has worn them since day 1) so I am going to try him with more traditional bedding, but don't know how much of it he should have. His room is about 18 degrees at night, if that makes a difference.
