Jamie,
kt was pretty clingy at that age (however, she has different issues all together). I wonder if some of the demands at school are more than she can handle right now.
She's of an age where she's expected to complete homework for school, chores at home (I'm sure) & other age appropriate requests.
I wonder if she's just isn't feeling a bit overwhelmed by this...add in a difficult child sibling, well.
Another thought, are you seeing any signs of puberty .... some girls start showing hormonal changes at this young age. Little hints here & there.
I agree, don't make a big deal of it. If easy child will talk, let her. In the meantime, if you can, let her be the "little girl" for a while. She'll overcome that need sooner than you think.
Just some things to consider.
