Hello! My 3m baby sleeps in my bedroom and when I put her to bed the heating is on at 22 degrees, but during the night the temp drops to 17-19 so I'm worried shes cold. She sleeps in a vest, baby grow and blanket. She has woken quite a lot tonight and is on the cooler side to touch (but not cold) however, I'm concerned that if I put her in a 2.5tog sleeping bag when she goes to bed it'll be too hot for her at that point. Any advice or experience would be very gratefully received!
