My 2 and half years daughter is showing toddler tantrums more these days. Saying no for everything and not eating and hurting herself banging her head and biting herself and hitting her 9 months old brother. I am worried with her behaviour. Is there anything I can recite and do any Amal to reduce her anger?

Kindly recite 5 times salawaat
Followed by following

Holy Quran 3:134
الَّذِينَ يُنفِقُونَ فِي السَّرَّاءِ وَالضَّرَّاءِ وَالْكَاظِمِينَ الْغَيْظَ وَالْعَافِينَ عَنِ النَّاسِ ۗ وَاللَّهُ يُحِبُّ الْمُحْسِنِينَ

Who spend [in the cause of Allah] during ease and hardship and who restrain anger and who pardon the people – and Allah loves the doers of good;

Holy Quran 21:107
وَمَا أَرْسَلْنَاكَ إِلَّا رَحْمَةً لِّلْعَالَمِينَ

And We have not sent you, [O Muhammad], except as a mercy to the worlds.

And surah qalam followed by 5 times salawaat
