I'm worried my child will wake up siblings in the house

This is a very common concern and it's an excuse lots of parents use not to get started. But you shouldn't let this stop you from improving sleep.

Lots of times, parents are surprised to find that siblings aren't disturbed at all when one child is crying - even if they share a wall. Once kids sleep, they typically sleep pretty hard.

But, if you're concerned, you have options:

- Build a "sound bubble." Make sure each child has a white noise machine and turn up the volume. You can even add another white noise machine or even a fan in the hallway or adjoining bathroom to help insulate any noise.

- Move a child temporarily. Feel free to move a sibling for the first couple days of the process. Have them sleep in a guest room, spare sofa or even have a "camp out" on the floor in your room. They won't be there forever and you can reward them for helping support their sibling through the sleep process.
