constitutional remedy

hello,

I am looking for some advice,my three year old daughter has been very slow to talk so after lots of research i was 100 per cent convinced her constitutional remedy was natrum muriaticum,which im also convinced matches my sons and also my own constitutional remedy. I have been very anxious for her to catch up with her peers when it comes to communicating.

As I self prescribed i started her on a very low dose and gave her natrum muriaticum 9ch three doses per day for three days. The first day she had extreme fatigue and had a one vomiting episode in the evening. She had no appetite and Ive never seen her sleep so well at night. The second day of dosing the same reaction,she was extremely tired and vomited at the exact same time and slept really well. I took this to be a good thing and continued dosing on the third day. No vomiting on the third day but the extreme tiredness persisted and she slept really well.
On the fourth day my daughter woke up like a new person.. she was full of energy,appetite back, communicating more than i have ever seen before and she was in great humour so I took a wait and see approach,stopped dosing, and for the following week she was speaking more than ever(we are bilingual and the weaker language has finally started to come through)I became very excited about her progress and shes been getting great reports fom her preschool but after a week of progress i feel that it has stalled quite a bit, i dont see other improvements coming through ...
what i would like to know is what to expect next,should i wait and be more patient, redose again soon or what to do to keep the progress moving...

Thank you for any advice
