My baby was away for 6 hours and he could have cared less 😭

I know I may sound silly for being sad about this. But my in laws watched him for 6 hours today. He's never been without me for more than an hour. He could have cared less! And then when I finally came to get him, my presence didn't even phase him. Actually, he wanted out of my arms the second I held him. At home when it's just me and him, all he wants is me around or me holding him. Can anyone reassure me or explain why?? 😂 Also, when I or anyone holds him, he is literally dead weight, doesn't cling at all and will sometimes straighten his legs out, but still prefers to be held. Is this normal or do most babies start to cling on by now?
