My two year old put himself to bed!!!

So I was showering too long lol and my two year old I decided I was taking too long so he crawled up in bed and pulled the sheet up himself and fell asleep.

My mattress is on the ground. My husband was sleeping already. My six year old was laying in our bed too. My bathroom is in my bedroom. And when I got out there was all three of them in the bed. The six year old the only one up. My littlest one was breastfed till his 2nd birthday. It’s been two months off the boob. So every night he has to sleep with his hand on the boob twiddling the nipple and his cheek on my chest feeling the warmth. My little guy!!!
