Firstly, I love my teddies! I don't care that I'm WAY past the age of having them, they're soft and comfy and have been with me since I was very young so I love being in bed with them haha!
Another thing I love is my dressing gown, I bought it from Marks & Spencer and it's really big and nice and fluffy, I look so frumpy in it but I'm too comfy in it to care! Also cosy socks are a must!
I usually watch TV catch up, YouTube or films on my laptop in bed or sometimes I look through old photos of past holidays etc.
Sometimes I'll have some treats with me too and if I'm feeling really lazy and in need of some real comfort I'll order a pizza! A hot chocolate is a must have for me on a lazy day too.
