My LO is 13.5 months and we just finished night #4 of Dr. Gordon's method. We co-sleep and she has been night nursing more frequently than ever, which is a problem for my 8-week pg bbs! Last night was definitely hard but she was in our arms the whole time she was upset. I couldn't stop thinking about people who let their babies CIO as I can't imagine how upset she was with us, let alone if she was in a dark room all alone. I hope this works!
