My 2 year old is performing at bed time

Hi everyone, 

Me and my husband need advice... 

My two year old used to go to bed without any fuss at all and would sleep happily and wake up 8:30 if we're lucky.. she hah 1 nap a day.. but now, she creates a use fuss and gets herself worked up when we put her to bed...she just sees her bed and grabs hold of us and starts crying... It's been going on now for 5 days!!:-(
