our dd has always been wonderful at going to bed and staying in bed, recently she is in and out of bed all night long excuse after excuse to come down stairs usually for a wee (bathroom is downstairs) and now all she wants to do is sleep with mummy and daddy which we dont mind now and then but its getting to every night, we take her back after a little while but she is back within 10 mins, is this normal behavior or a phase they go through, she says she is scared in her room of what she dosent know and she also says its not fair that mummy and daddy have each other at night time and she has to sleep alone...any ideas.....
