No, the womb is a brilliant sound barrier for the baby. My 7 year old is very loud around my bump too!
My bf likes to blow raspberries on my belly, like his way of talking to her. I thought it might be affecting the baby somehow. I started my NST's last week and the nurse said if the baby doesn't move they "shock" my belly with a lil vibratory which is essentially blowing raspberries on my belly lol. Like Polly said, the womb is amazing.
