I am in the exact same situation! Help, people! Our EASY is quite similar, and there are NW all over the placem, especially between 2 and 5, most nights one long NW from 30 min to 1hour30... I am going INSANE. LO (11 monhts) used to fall asleep within minutes until some weeks ago, now needs a lot longer, he seems to have trouble to wind down. In the night he keeps waking up, and sometimes I have to pick him up and rock. He has just started to walk, but the bad sleeping habits have been there for MONTHS.
Also he seems kind of addicted to the teething cream that I gave him when he was teething.
Sometimes he won't stop complaining until he gets it. And that way he gets is several times per night. PROP???!!!
I was wondering whether walk in/walk out could be an approach? Has anybody tried in this particular situation?
