Hi Leena and welcome,
Can you post his routine for me?
It sounds as if maybe your lo is overtired which could be causing the early wakes. Have you tried to extend naps? At his age he sould be getting 2, 1.5 hour naps.
It also sounds as if the paci might be a problem. Do you have to replace it during naps and nighttime sleep? Do you think it is a prop?
