Twins always have an inseparable bond that was probably developed months before they were born. A mom uploaded an adorable video on YouTube showing her twins with one of the most extraordinary relationships.
In the clip, the six-week-old twins can be seen snuggled together in their cot. When one of the babies suddenly cries, his sister lets him place her hand in his mouth which calms and soothes him. The sweet twin moment was captured by a baby monitor.
