I am/ was 100% in your shoes...but my second is due later in June. I started this process in January because I figured it may take a while. I went straight to a twin bed with bed rails on either side (only way in/out is at bottom of bed where we place pillows so she doesn't fall out). The SAME behaviors you mentioned occurred with us too... I didn't let it go past 1 week (that's all I could handle) before we went through the "cry it out" phase. Thankfully this lasted less than one week. The first time was 13 minutes, second time 7 minutes, third night was 5 minutes, and so on. After that week we were also able to successfully get rid of the pacifier! She's been sleeping great UNTIL recently (is now 24 mos. old)...all of a sudden she refuses to go to bed about once/ every week... on these nights we again have her cry it out (after getting every excuse in the book from her including "mommy want to lay by me?") You can comfort them, meet all their needs, communicate with them, replay their day, sing songs, etc.. it's the same thing each time. I believe it's part power struggle as they grow & part due to various things like: getting 2 yr molars, seasonal allergies, anxieties of a new sibling's arrival, being scared of something from a tv show/book, her own imagination working over time, etc! Follow your gut feeling... and try not to create a pattern that will be unhealthy for YOU especially as the new baby arrives. When I hear her cry I think to myself "what if I was feeding the baby right now? I can't just stop and tend to her needs...she's got to wait/she'll be fine"... and usually after 10-15minutes, she's done crying. If not, check in on her at least once...but don't stay or talk much if possible. Reassure him/her, wipe their tears, and tell her it's "time for night." Good luck!
