Ohhh how frustrating - but how silly of you not to realise that now you have a bump pretty much everyone else is an expert about you, and your IQ's just dropped significantly.

Try not to worry about it, something I've found very valuable to remember is that people's comments say more about them than about you. What this comment says about this man is that he doesn't understand what a birth centre is, and is also happy to make a comment based on his incorrect assumptions.

There's not much safer than a gentle birth centre birth really, my first bub was born in water in a birth centre and I can't rate birth centres highly enough.
