The beginning of the Oedipal complex?

Recently Gabe gets jealous when Mommy and Daddy are hugging.   It’s kind of fun.   Tonight I was playing with Gabe on the bed when Steph came up to join us.   As soon as I hugged her, though, Gabe started to whine and threw his whole body between us, until he was bear hugging Stephanie’s head.   I wonder, when does the Oedipal complex start showing itself?   Or am I the one with the issues — is there such as thing as a Liaus complex??
