Lying here awake worrying about my middle DD who is 9 and who I think is showing signs of something and just can't put my finger on it...
She is a very happy, quirky child and very active but recently a few signs and symptoms/signs have made me sit up and start to wonder if a Dr trip and tests are needed...
She is and always has been a huge worrier, she does a two sports quite well and one has a fair amount of risk to it but I have never known a child to panic and risk assess as much as she does to every inch of detail to the point that we have wondered if this sport is for her.
That being said she loves it with all her heart and we have now all invested a lot of time and effort and money into it.
She is painfully thin, 9th centile when born and pretty sure she still would be if checked. I had problems feeding her past 4 months when my supply seemed to miraculously drop and she dropped down to the 2nd centile, lots of pressure to stop and put her onto special milk but she was still happy/alert/wet nappies etc so preservered with the help of domperidone and managed to get to 14 months, now wonder if there was a tie that wasn't picked up...
Speech therapy from 4 (speech bad and only a selected few that could really understand her) it worked a treat but I have always felt there what a slight lisp or thickness still in her words that didn't go. It's hard when it's your child to just think that it's them and not to wonder if something more needs done (speech therapy wise) but I constantly need to tell her to slow down with her words as often still can't understand what she is saying...
I have mentioned to various class teachers and nothing has ever come of if it and again just wondered if part of her although like before not unconvinced there isn't a tie...
She is also very nasally and noisy (best way to describe it) with her mouth, I really can't stand to have her read something or just sit over my ear or shoulder because she is constantly snorting (again best word for it) or making noise with her mouth, often her fingers will be there too, not necessarily in her mouth but playing with lips etc...
I think hearing is quite bad, we do have an appointment to get this checked but due to usual baby/school checks and then a routine one with speech therapy not convinced they are going to find anything...
Constant mouth ulcers, like at least 2 bad ones every 3 weeks, she has her own part on a shelf in fridge with various sprays and liquids to help when one appears. I have mentioned this to the Doc a few times but no one has ever seemed very concerned, just put down to being run down, just one of those things!!
Always something in her mouth, when she was 2 she choked on a two pence piece, absoloutly horrifying at the time but it's just carried on to a whole childhood of chewing on things she shouldn't, occasionall it's big things, Barbie shoes, anything squishy but mostly it's tiny bits of paper...yesterday while doing her sport I asked her what was in her mouth and its was 3 little bits of scrunched up foil.
I really try to stay patient with her as she is quite a gentle little thing and realise as a habit which is mildly OCD shouting will get me nowhere but I lost it with her with worry and what a stupid thing it was to do with the risk of her choking was huge!!
Food stealing!! This really worries me for obvious reasons, 
She is in a bedroom downstairs which means she had acsess to the kitchen at night and very often I will be making her bed in the morning and there will be wrappers, crumbs, trails of cereal either hiden or swept into piles. This in itself I guess is quite child like but it's the lying about it and continuation for the last 6 months, even after various discussions/punishments/privileges removed (you name it we have tried) that really worries me. She will be really upset/apologetic at the time but then a few days later it happens again...
I really worry that this is quite worrying behaviour and that the signs of an unhealthy relationship with food and control and starting to form...
Constant nail biter and has been from many years, I can't remember the last time I cut her nails, toes as well! 
I do very rarely see her do it and we used to joke when she was really little that she had magic self cutting nails but now worry this is just something she has always done and again had developed into quite a bad habit and worry/stress reliever...
Sorry for the long post, I think I just had to write it all down to see myself that behaviour and above signs definitely needs checking, I do find it frustrating that a lot of it I have mentioned to various Drs/teachers etc and I'm always fobbed off or told "just one of those things" and because none of it is life threatening I just didn't see the point of persuing.
She is such a lovely little girl and we always joke (between me and OH) that for an only child she gets more time, attention and money spent on her than the other two put together...Basically I don't think she is being overlooked or lacking in any love or affection!!
Can anyone relate or have any advice and do you think there is an issue or is it all stages and habits that she will outgrow?
