L.S.
All my babies shared a room and still do. The new borns slept in a bassinet next to my bed until they our grew it which wasn't long. Then into a crib and then into a toddler bed and then into a twin bed. My parents gave me good advice. Always get your child used to sleeping with noise around, then they can sleep anywhere. If it has to be absolutely quiet, then you are in trouble. You can't take them anywhere because it is never absolutely quiet anywhere except home. I am absolutely sure they will get used to it. My kids sleep through thunderstorms and their little brothers bad dreams. And always have. THey are 13, 11 1/2 and 8 1/2 and all still share a room. The ocean sounds are great. We use little fans at each bedside for white noise. But they can and do fall asleep in a variety of settings. Camping, during movies, with the radio, snoring from the other brother, during rain storms, and mom puttering around the house after their bedtime.
