13 week old question

At why age did your babies start holding toys and things. Somebody made a comment that my son should be holding toys and be interested in toys by now. To be fair he will try and does hold them but drops them after a few seconds. However he will hold his muslin cloths for hours on end. They seem to be a comforter for him. I guess I’m just worried he maybe behind after that comment made to me. He’s 13 weeks old today.
