dh and i have different views on this, dh thinks its very much just childish behaviour.
dd is 6. teacher came to us at the end of friday (i feel so bad that there is already something the teacher needs to talk to me about! very awkward indeed) that dd had drawn over her knee in red pen (she wears tights) and when teacher noticed it when they were on the floor, as thats where they all sit when teacher talks, she asked if that was pen or blood on her knee dd said blood so teacher asked her to wait for a bit before going out to break as she wants to take her to the medical lady, medical lady asked dd to remove tights so dd did and medical lady pointed out it was pen and dd kept insisting it wasnt? 
nothing really happened and dd went back to class and they didnt say any more to dd until teacher spoke to me at the end of the day. i asked dd and she says she only wanted a plaster!! is this just a regular kid? dh thinks so im a bit more on the edge thinking its a bit extrme
