HELP with a 6 month old and 2 1/2sleeping in the same room"

Hi,does anyone have any experience or tips with 2 kids sharing a room? We are having major sleep issues with the baby (and now she is teething, oh joy!)and how it is effecting the 2 1/2. We have 2 bedrooms on each level of the house and we don't want to move Noelle downstairs by herself since it's on the other side of the house. Noelle doesn't always wake up but I know we are rushing to Lindsey's side much quicker at this age than we did with Noe. Sorry if this is rambling and doesn't make sense.. We are getting hardly any sleep and it is driving us nuts.. Just wondering if anyone has any good advice for me besides moving or moving Noe downstairs, neither of which is a good alternative for us right now..

As always, thanks so much!!!
