Although fasting for the entire month becomes obligatory at the age of puberty, it is common practice for Muslim children to begin to fast before this age to become progressively accustomed by the age of puberty. Most children aged 10 and 11 (years 5 & 6) are likely to fast all 30 days. Children are enthusiastic and get a great sense of achievement in joining their families in taking part in the spirit of Ramadan and often begin at a younger age.
