L.M.
I too have the same set up as you! The one thing I figured out is that I can not feed her solids after 3 pm. She too is exclusively breast fed, but I started solids on Oct. 22nd. I was only feeding her in the morning in case she had a reaction. Then I started feeding her squash in the morning, then rice in the evening. She was not going to sleep until 11 or later! Then I changed it to just giving her "lunch" of a pureed veggie and rice. She now sleeps at 830 again. Mind you, I co sleep and just bought the "no cry sleep solution". We are trying to get her into the cosleeper and out of our bed.. the crib is in the living room.. LOL gotta love NYC
