Input: Backstory: So I have this aunt with 4 boys that posts things about anti-vaxx. That's fine and all because it's your children. Her kids are cool and I relate with one of them very well since we both enjoy Game Theory. I haven't received any shots for quite awhile (27m) and don't think I need anymore. But I did receive them until I was about 10 years old and think they should be induced for the beginning of someone's life. 

Situation: In about 4 months time, I will have a baby of my own. My wife said that our cousins will want to hold the baby and be around her. 

My thoughts are "they won't be around my kid until my daughter has built up an immune system and has gotten her shots." 

The cousins are four boys who didn't get to choose to be or not to be vaccinated, but these kids rarely get told no. Not sure about the aunt but I feel she has rarely been told no also. I worry that my wife and grandmother will go with having our kids meet without my concerns effecting their decision. 

AITA for telling my cousins they can't see my baby until she gets her shots and builds up an immune system? 

Also, when would be enough time for her immune system to be strong enough? TIA

Cousins are 3, 8,10, 14.

not letting my wife's cousin see my future child because they are not vaccinated
