Yep. If you DF at 11pm, which I used to do, then your lo should not wake until 4amish. So instead of two night wakings, you will only have one. Then as your lo can last a bit longer, you will do that one feed later and later, until you don't have to do it at all.
The Dreamfeed worked great for us, go ahead and try it. Also I loved doing that feed, she was soo peaceful.
