Hi Cindy. I am new here, too. Actually newer than you, and inexperienced.
Didn't know you could buy an is it a completed baby doll that you bought? If so, how come it doesn't have the eyes in yet? If you are really clueless, and as inexperienced as I am, you can start by watching videos on youtube until you can get a dvd/dvds on reborning which i would recommend even if we have the free ones on youtube, just so you can see the sequencing.
If you got a doll kit, like how they usually come (blank/unpainted, no hair, no eyes, etc, only head, arms and legs, or with body), then how come the head is already attached but doll has no eyes yet? What level are you in reborning, are you as inexperienced as I am?
PS Just in case you haven't watched them already, there are youtube videos on reborning such as painting with genesis heat set paints, purple washing, understanding the color wheel (although I haven't watched the entire thing), hair rooting, weighting the reborn doll, etc by Nikki Holland, etc. oh, and yes, your question, inserting eyes on a reborn doll, i believe there's at least one there, too.
Perhaps you could also post your questions on the forum with "mentoring" in its topic/description. I hope i'm right about this :-), just trying to help.
