My DD1 who is six is incresingly losing her appetite. She has always been a bit picky but she seems worse than ever, to the extent that she is not even interested in treats such as happy meals, sweets etc. I decided to weigh her today and was quite shocked that she is only 4 stone 5. Her height is 127cm (ahe is tall for her age) I then weighed DD2 who is nearly 4 and she weight 4'3, only 2 pounds less than her sister (height 104cm). Is there anyone who can give me advice as to what is normal/ not normal as i'm so worried. She did have a heart murmer when she was born which I was told had gone after about 8 months. However when she had a cough a year ago it was heard again. The gp said it didn't matter as she looked well. Am I being paranoid? She has also started waking in the night saying she is lonely. I am unsure if what is going on in psychological or there realy is something wrong with her. Can you wise people tell me whether I should go back to GP? Or maybe the HV? If I go to the docs, normally end up feeling like i'm fussing over nothing, not that I take them very often.
