Toddler crying at naptime and bedtime.

My 2.5 year old woke up crying in the middle of the night last week and was all upset and wanted to sleep in my bed. She's still in her crib because she's always been comfortable in there and never tries to climb out. Since last week she gets upset when it's naptime or bedtime and will cry for a while before finally giving up and falling asleep. Then she wakes up early to sleep the early hours in my bed. We have a regular bedtime routine, she has white noise music and a small nightlight. I'm wondering if I should be transitioning her to a toddler bed now or getting more lights in there. I'm at a loss as to what to do. As a side note, I've noticed her asking me to put the lights on more, so she might be afraid of the dark. And she does say scared. via /r/Parenting http://ift.tt/29fVtHM
