Hi S.. I am a SAHM of 3....Ages 8yrs, 5yrs, and 10 months. My daughter was and still does the same thing when I put he down for a nap or bedtime. AT first I was picking her back up, but it would backfire on me because she would then think she was up to play again. I just started lying her down, and as soon as she would go to get up I would lie her down again, and say it was time to go night-night. I would leave the room, and of course she would cry. I would wait 2 minutes, and then go back in, and hug her(W/O picking her up), and lie her back down again. I gradually extended the time of going back in to reassure her...up to 5 mintues. She now knows it is time for bed, and still doesn't always want to lie down. She does not get all upset like she used to, and eventually goes to sleep within 10 minutes. I have observed her from the door(w/o her seeing me)to see what she does. She still stands up, and tries shaking her crib, bounces up and down, talks, etc. She plays with her musical fish toy that is attached to her crib. I am sure you will get there. Sometimes these things are just a process....consistancy is KEY! Good luck to you!
