As a follower (ma'mum)
أُصَلِّيْ سُنَّةَ التَّرَاوِيْحِ رَكْعَتَيْنِ مُسْتَقْبِلَ الْقِبْلَةِ مَأْمُوْمًا لِلّٰهِ تَعَالَى
Ushallii sunnatat-taraawiihi rak'ataini mustaqbilal-qiblati ma'muuman lillaahi ta'aalaa
I intend to pray the recommended Tarawih, two rak'ah, facing the qibla, as a follower, for Allah the Exalted.
When & how
After the Isha prayer throughout the nights of Ramadan, usually in congregation at the mosque. Prayed two rak'ah at a time.
For your little one
Bringing a child for a few rak'ah of Tarawih (as their age allows) grows a love for the mosque and the spirit of Ramadan.
