Video of newborn twins soothing each other will tug at your heartstrings

[These two are attached at the thumb, figuratively speaking, of course/YouTube]

A new mother of twins posted a video to YouTube, that captures one of the twins helping to calm his brother, who is having a little fit.

Luckily for the mother, her six-week-old daughter was ready to swoop in to help her twin brother, all while staying sound asleep.

The sister’s hand is conveniently situated right by her brother’s mouth, which halts his cries once he starts to suckle on her thumb.

Fair warning, this may be too cute for words.
