I left the two of them in bed to prepare breakfast. When I am done, I found them in this position. I am amazed that the little one can continue sleeping with the weight on her body. She became a human bolster that morning.
And this is not the first time I witness sure cute sleeping position. It happened to the rest of my children when they were younger. Once I am not sleeping in between them, the smaller ones will become the human bolster. 
If not, my legs will be their bolster.
Stumble it!
wah…tat bolster so CHUBBY and warm eh!! I like!!
