I asked her if she had learned to respect my wishes. She told me I was being unreasonable and that she would witness to my son. I then flat out told her she could not see him.
Your house, your baby, your rules. She can think that your position is "unreasonable" all she wants, you still control access, and until she gets that you are serious about her not witnessing to your son, she doesn't get to see him. Period.
I hope Ryan stands behind you on this. Shame on your mom for trying to go through him to get access to the baby.
If she continues to refer to your position as "unreasonable", you can call her position "unreasonable" too. Let's face it, only a fanatic would think of "witnessing" to a little baby. Can we say "restraining order"??
