I've been a Vegetarain all my life, and my mom was when she was pregnant with me.
So My Question is, Will affect my baby's diet when he grows older?
My body has grown an Allergic reaction to meat so,
Will that pass on to him?
No. Your eating will affect the baby, of course, but your vegetarianism won't be passed onto the baby. Living a vegetarian lifestyle will be what the baby will learn as s/he grows up - just as your mom passed her vegetarian views to you.
It isn't so much that you are allergic to meat. It makes you feel sick because it is harder to digest than vegetables/fruits/grains.
