Yes it's normal, and no you aren't wierd for wanting that. My iLs were going to camp outside too - like HELL!
I told my DH if he didn't want a divorce, he only rang them when i said he could....and that was well after it had all started. Who wants the pressure of a waiting audience. He was also told to tell them explicitly to STAY AT HOME.
They did - but then they showed up at 10am the next day, right when I stood up to have a shower and nealry bled to death....they thought they'd just take my new baby downstairs. Yep when I died maybe. So I got the midwives to put a sign up on her cot for no-one except us to pick her up.

You and SHell make an agreement. You aren't obliged to tell anyone when you are in labour/go to hossy. It's not controlling, it's being in control of your situation. They aren't in control, they are guests in the situation and like good guests should know they need to be invited.
