Not sure there is much that can be done here, but just wondered if anyone had had a similar experience.
DD was a prolific thumb-sucker since 3 months, was sucking it all day long, during meals, etc. She had this very cute self-soothing thing where she sucked thumb and rubbed her hair with the other hand which was brilliant - she was an excellent sleeper and I think this was partly why.
Just realised that I haven't noticed her do it in the past few days and cooincidentally suddenly her sleep is a disaster and I am having to feed her to sleep (not a fan of crying!).
Any ideas???
