That's one reason that keeping the expectant Mom in a healthy sonic environment is so important. Try to avoid:
- arguing and loud, disagreeable conversations
- fireworks and explosions
- loud music of any kind whether rap, rock and roll or even classical
- sudden or persistant drilling, hammering or other such noises
What's the best kind of sonic environment?
- calming soothing conversations or music
- singing and talking to baby, beginning in the second trimester
- happy and positive interactions in Mom's day
- keep any conflict to a minimum
Of course there are babies born all the time into conflictual families, even in war zones, and they survive and even thrive! Humans are resilient creatures and can withstand unbelievable odds and hardships. But if you want to provide the optimal environment, follow as many of these suggestions as you can!
