two years baby not eating solid- loosing weight

two years baby girl not eating any solid food for last more than one year-
loosing weight.............. request help
hi;
my grand daughter is under going some serious problem, which is still undiagnosed by the allopaths as well as a couple of homeopaths over here. she is only two years old and was absolutely fine and healthy at the time of birth and even there after till she was about 8 months. in the process of teething she started discarding eating solid food and since then she is loosing weight day by day because she is not eating at all any solid food for the last more than one year. she is being fed on milk mixed with some grain-cereals and that too only when she is in deep sleep. her brief history is detailed here under :-

1.she is a test tube baby girl because her mother could not conceive in a natural way for about 10 years;

2.she was delivered by c-section , because her mother could not deliver her in a natural way too;
3. she was just normal at time of birth - weighing almost 7lbs;
4.she was taking normal breast feed as well as formula milk thereafter, just as a normal baby;
5.till the age of about 7-8 months, she was quite healthy and taking every food - may it be some solid food, fruits
and cereals, eggs and juices etc; and she started cutting teeth at appropriate time;
6. during this period she started avoiding some food stuff and we thought it might be due to her teething prob.; but she gradually started avoiding even milk
7. also she is extremely scarry of hard sounds - like sudden dropping of some thing,
whistel of cooker, any unseen noise, scenes of voilence, loud voices, fights shadows, movements of any thing in darkness etc as if she is afraid of all this. she will throw away every thing which she does not like to eat or does not like to play like with some of the toys etc. and rather would spoil/ throw away all such things;a very much destructive action;
i, just want to bring to your notice some additional facts too-
> she has lost 3lbs of her weight during last one year; instead of gaining weight during this period.
> she has occasional complaint of acute constipation too- stool like hard small balls; but after initial few balls and thereafter followed by her stool coming out like normal
> she moans / groans a lot while asleep, as if she is in great pain some where in her body - may be legs ortummy etc; and lastly, during day time she rubs her buttucks (bottoms) on silky or blanket surfaces - whenever she finds time and
also bites blankets etc.
> otherwise, she is quite energetic and is of very good temperament. it looks like that she is some what hyper type - too much active and fast in activities but talks only a couple of words(which could be understood properly) and rest of her talking is just vague - being not under-standable; though she is fast & too talkative;however she understands every instruction given to her; but she will ask for only with hand signs;
> during whole of the day she can be fed just couple of times with milk plus cereal(2spoons) plus gerber's fruit jelly (2 -3 spoons) and that too only when she is asleep and thus
she remains under-fed throughout the day;though during night time we do feed her three times with milk plus cereal etc;
> she likes to eat green peas,beans, cucumber, apple, bannana etc but just couple of bites;
> she likes ice cream, drinks cold water a lot of times but only a couple of sips each time;
> otherwise, in general she is of a very cheerful nature, always busy in playing;
> her lips are generally dry but feet and hands cold, she never tolerates cover during sleep - whether in winter or summer
8. by the grace of god, she was blessed with a younger brother- almost eleven months after her birth; but she never showed any sign of hatred or madness towards him; because of extra affections shown towards her instead of her younger brother; she never trieid to hurt him any time; still we feel that she might have some madness on this aspect too(just our imagination)because her eating behavior started well before his birth.
9. this caused worries for the family and we consulted doctors; initially allopath- her peditrician and there after specialists too but all said there is no problem and we should try to make her eat; but with no results, and she started loosing weight and within this one
year period, instead of gaining weight- she has lost about 3lbs of her weight.
10. as far homeopathy is concerned,as usual, she was administered calc. phos 6x for teething problem but when this problem started she was given chamom.6x for three weeks, thereafter a single dose of chamom. 200c. but all with no significant results except that she did stop crying in the middle of nights but as far eating concerns,there's no improvement- no considerable results. she was also given americana lutea 6x for about 3 weeks; in addition to cina 200 for a week -thereafter, followed by ant. crud 200 in the morning ;
and cheldonium 200 in evg for a week;
11. thereafter some one suggested us to see a homeopath in canada ; who stopped her all medications and instead based his treatment on her mental symptoms (the fear-phsychosis)
which he thinks of most important factor as the past of her parents was not that happy one and their inter-behavior etc might have depressed her and consequentially landed her in this problem; and thus prescribed his own homeo prescription- (name unknown to us) and we are continuing the same for the last about three months; but the child's eating problem still same; and she is still not improving in her health-
although we feel that further deterioration in her health is stopped.

(worth to point out that during last one year,she had a very disturbed sleep during the
night and she used to toss up violently here & there in the bed through out the night
particularly in the first half of night; and started crying in the middle of the night around 2-3 am very aggressively,squeezing her stomach and thrusting her legs as if she is feeling some aching either in her stomach or legs; and it is very hard for an hour or so to console her and make her sleep; but thereafter say 5 am onwards, she goes in deep
sleep and gets up around 10 am or so; but now this problem is almost over);

so my earnest rquest is that if some of hon'ble homeopaths on this forum could come forward to help this little angel so that she starts eating regular food and live a healthy life.
i am ready to furnish any other information in this respect at any time;
