LO was doing great for a while sleeping about 9pm-5am, and then he got a stomach bug and has been off that schedule since. Because of work I occasionally have to spend the night with him at my parents house, they live out in the country and it's quiet all night /morning there and he sleeps fantastic, typically 9pm-6-7am. However we live in a loud city and I'm desperate for some real sleep, he wakes up multiple times while we are at home (last night: 1:30am, 3:15am, and 6:30am). Any one else live in a loud area? Did you do anything specific to help baby sleep through the noise?
