It's a mom's pride and joy when she sees her children helping each other out. Thankfully, they get it on video on, too.
"My six-week-old fussed when I went in the other room so his twin sister took care of the situation," the mom wrote in the description of the video uploaded to Youtube.
The twins can be seen huddled together with the little girl sleeping on her side with her arm resting on her brother. The little boy, on the other hand, isn't too pleased about bedtime and cries.
Luckily, sister's thumb is within reach and saves the day! He reaches for it and starts to suck, immediately calming him down. His eyes slowly start to close, and he gurgles in contentment. Whether the help was unintentional or not, it's still too darn adorable.
