Read this to the child... always...
يَا أَيُّهَا الَّذِينَ آمَنُوا اصْبِرُوا وَصَابِرُوا وَرَابِطُوا وَاتَّقُوا اللَّهَ لَعَلَّكُمْ تُفْلِحُونَ
O ye who believe! persevere in patience and constancy: vie in such perseverance; strengthen each other; and fear Allah; that ye may prosper.
Read this and blow towards the upper forehead.
Another one I used to do for my daughter, Balqis. She had difficulty reading the Al-Quran so, following my mum's advise I read surah Ar-Ra'd to some water n gave her to drink. I did this many times. Alhdmulillah, she now reads the Al-Quran even better than me and even memorizes 6 long surahs. Yassin, Al-Waqi'ah, Ar-Rahman, and others.
