3 Y/O not sleeping in own bed
So I have a 3 year old girl, she just turned three a few months ago.
She has her own room with a toddler bed, however, she gets up in the middle of the night and goes to the couch and sleeps there [I don't hear her].
It's happened before, but it's been happeneing more recently lately.
Should I worry? Is this just another stage kids go through?
Also a week ago she went to go through some trash in the kitchen and ran out saying "ahhh scary monster". It was actually the vent behind the stove that allows fresh air to come in [it sometimes makes this noise when the wind is blowing]. I tried to explain that to her but still she's scared to go into the kitchen alone.
I don't know where she picked up this whole "scary monster" thing. She hardly watches t.v.
Could it be that she's scared of her room? She's been sleeping on her own for most of her life [she slept with me briefly when she was a newborn].
Well if you have and ideas or suggestions that would be great, thanks!
