well first of all, what we always recommend when babies have "a sleep issue" is do do everything just as normal. Any deviation from normal, such as picking up will confuse baby more. Babies will have period when they question sleeping or eating or something else, in the only way they can - since they do not have word yet. Our jobs as parents are to reassure that yes, Im still in charge, I know best, you are safe in my hands, It really is nap time. So stay with your routines.
Dark room, no traffic in her room, no picking up, just jingles or music. Be consistent.
Then, whines all day = is usually a sign of tiredness. And over tiredness by nap time can def make it hard to fall asleep. I think it might be time to introduce that 12 h night. and then have a nap in the middle of the day for at least 1.5 h to give 13.5 h totally.
