Do not pick her up. She is testing the waters right now and searching for boundaries. Make sure she is only taking one nap a day now and maybe adjust the time so she is tired, like right after lunch and just for a few hours. At 17 mos she should be getting about 14 or so hours a day total. Just make a fun new routine for her, stay very consistent and do the naps at the same time every day. Do not give into tantrums and do give her clear boundaries that are easy for her to understand, even starting time out now. Serve her what you serve her and nothing else. Do not let her snack too much especially before meals and if she is hungry reoffer her what she wouldn't eat earlier. Right now if you nip the finicky eating it will get better, if not it will get worse!
Girls I can say are more emotional and dramatic with tantrums, I have a almost seven year old girl and though there are rarely tantrums I can say it was much more "dramatic" then it was with my son who is almost four. Even now she can really get upset over little stuff and my son is a lot more laid back, hee hee.
Just be consitent and patient and don't give in to her. Right now is the best and most crucial time to teach her when it is bedtime it is bedtime, no exceptions.
Try doing a bath, brushing teeth, getting into jammies and reading stories all snuggled before bedtime every single night or something that is the same every night. She will get her brain geared up around what is happening and that it is a que for bedtime.
Good luck it will pass, girls stay dramatic but it lessens! :)
