Hi Bryony,
Thanks for all the advices!
I started to feel that the dummy is becoming a prop long time ago but I don't know how to teach her fall asleep without it...
Regarding her late bedtime - she is not tired before that, and if she falls a sleep before 8 PM she wakes up very very early - around 5 AM - it's too early for her and for us!
in the afternoon nap I don't wake her up, and she's not falls back to sleep, she starts to smile and talk, and wakes up cheerful so I think its enough for her...
I think my only solution is to get rid of the dummy - but - isn't she too small for that? it calms her and I feel she needs it..
