Update for Doctor Mahfooz or Mani Jee or other expert

I wanted to update the case, that you helped me with.

This is what I originally wrote and asked help for:

My oldest son is 4 years old, he has several issues that I hope homeopathy can help us resolve. My son is grinding his teeth in sleep, before going to sleep and when he is angry. He also bites on his finger nails all the time, I have to tell him literally all the time to take his fingers out of his mouth. He started biting his fingers when I stopped giving him his pacifier at the age of 8 months. He also has the issue of bed wetting, he does that closer to the morning, and sometimes during day sleep. A week ago, he started peeing on the floor during wake hours, even though he would go to the bathroom as well. He has loss of appetite, complaining of stomach ache, I do not think though that he really has stomach ache. He used to love to eat soups, not anymore though. He never drinks any milk, does not like eggs and does not eat mushrooms. He does not drink any juice or tea, he only drinks water. He hates pastry and refuses ice cream.He likes noodles, rice, chocolate. He is not constipated and has never been. He was born full term, but my labor with him was very fast, he was born within 3 hours, during pregnancy I had the threat of miscarriage. He was slow, he sat down started rolling at 4 months and sat down at 8 months later than supposed, but started walking at 1 year, also he started talking later than most kids, at the age of 2, but I am not sure if that happened because he is bilingual. He was immunized last at the age of 6 months, with hepatitis, DTaP and polio. After that he felt really bad for couple months, he was not active and did not want to move and felt like lying only. So I stopped any further immunization. He is a healthy kid, but he is prone to false croup, when he can hardly breath. He does not like to sleep under the blanket, and his head sweats when he sleeps. He picks his nose mostly when I read him before bedtime. He is scared of darkness and often he runs to sleep with us. He has always been a good sleeper, but he has always needed me by his side, since he was a baby. He is inattentive, as in he does not listen to what we tell him and does not comply, he likes to run around instead of listening to coach during sports practices. He cries easily, if he can not get his toy out of box, he will cry and yell for me, he will cry if we take a toy away from him, and when he gets mad he throws toys and things around the house. He is very talkative. At the same time he is not aggressive. And he is attentive when I read him books, he loves to read and can sit and listen for hours. We would like to get help with these symptoms: nail biting, teeth grinding, bed wetting, yelling, throwing toys around, easily excited, not listening and not complying, nose picking, scare of darkness, and loss of appetite.

I followed your advice and gave my son Thuja 200 for vaccination effects, then Calc Carb 5 pills in the morning, and Silicia for the night.

And the update is

As advised I gave my son the 1 dose of Thuja 200, and I waited for 15 days before proceeding with Calc Carb and Silicia.
After Thuja I noticed improvement in finger nail biting and teeth grinding, the child almost did not bite his fingernails and stopped grinding his teeth during the night. In 6 days after I gave him the dose of Thuja, he got sick with upper respiratory tract infection and he had very high fever for 5 days, so I had to give him paracetamol several times, as well as homeopathic syrup for cough. He started biting his finger nails again, but not as often as before. I proceeded with treatment as advised, I was giving him Calc Carb in the morning and Silicia before bed time. He stopped failing to get to the bathroom during the day time, he is much calmer now, and listens more. He is still very energetic, and when we are at practice and he is around other kids, he gets distracted and may run away, but the treatment helped us a lot, it is easier to discuss with him and come to common terms. His head does not get as sweaty during night as it did before. He falls asleep in his room, even though he is still scared of darkness, I leave the door open and turn on the light behind the door. Thank you very much.

Could you recommend me further treatment please?
Is there anything else I should be giving him to maintain the achieved results? I am worried, because the beginning of May he is going to preschool, and I want him to listen to teachers there and do good, and not to get stressed out. And also I wanted to ask you for advice, my son is prone to false croup, which means he gets sick and then during night time he can not breath. Usually I turn on the hot steam humidifier to make it easier for him, but couple times it was so bad that we took him to emergency care, and there they gave him bronchodialators, but they did not work very well.Is there something I can give him for croup? And to help his immune system adapt to preschool, so that he does not get sick very often.

Thank you very much
