I have had a similar problem. All my children went to bed and slept well until we moved. Ever since, they have not done nearly as well. It's been a long time too! But I have a wonderfully large family, ranging in age from 3 to 20, so I have learned that they always outgrow these things, so I don't sweat it. Here are some things to look for: First of all, if she if only fussing after she lays down, it may be that she has a build-up of fluid in her ear, or even an infection in her ear. This is very painful, and WORTHY of screaming about. I would definitely bring her to her doctor to make sure that her ears are not the problem. If that is not it, here are more ideas: Is there something in the room she sleeps in that might be scary to her at night? Turn off the lights and look around it - from the level she is at. Are there different noises in the house from your old one? It may be worth your while to purchase a noise machine, you can get them for around $20 or less on Ebay.com. This may seem obvious, but is she hungry? She could be going through a growth spurt. My daughter's baby started waking up every hour to nurse at seven months after previously sleeping well. It took my daughter two months to realize that she had almost no milk - she just assumed she was making plenty of milk (in her case though, she was also pregnant, so that must have helped to dry up her milk). Also, if she is not currently sleeping in the same room as you are, consider moving her in with you for a while. Even if it is not what you prefer, it would be worth it for you to get some more rest, and for her to not be frightened. Many cultures around the world have their children in the same room with them naturally. It just makes sense - it's easier to care for them for one thing. You could put a baby bunk or co-sleeper next to your bed. I will post some links in my sources. In the meantime, try to catch some extra sleep yourself during the day with your baby, or perhaps in the early evening when someone else can watch your baby for a bit; if daytime doesn't work out for you.
