I'm listening in as we're in the same boat. Went from just one NW after the DF, usually between 3-5am....then shortly after 3 months it all went to .... you know! I'm thinking it is really common around this age too, as I've been reading lots of posts re: NWings around 4 months old. It really stinks, especially when you've been used to only one or two NWings. I'm just hoping it ends soon, but haven't been reading much from people about when to expect things to return back to normal!!
