My 2 1/2 year old is a very good sleeper (started sleeping through at only 5 weeks old and it’s still the same). She is however very active and has been moving around in her cot a lot so that she was still in her sleeping bag. I started using a pillow recently and she has been wiggling around a bit less. I then thought it’s time to start introducing her to a duvet but was concerned about her kicking off the duvet and getting cold. Well, what can I say? I heard about Fidgetbum
