Sleeping buddies

I have a hard time to put Zach and Jake in their beds. Then I decide to put their beds side-by-side. Zach love to hold on something to get himself to sleep or he will suck his thumb while holding in his ears, while Jake love to keep himself warm inside my arms, once they fall asleep, is only when I left their bedroom. This time Zach just had his brother's hand to make himself fall asleep. I thought this is a sweet pictures of them.
