As a Muslim child, it is obligatory to follow some rules of Islam like the grown ups. The rules of Islam applies on people of every age, Some things we have to do by the order of Allah like respecting elders, getting up early to say the prayers, refrain from speaking lies and take part in education.
When you get up early in the morning you are supposed to say this:
Alhamdu lillahilladhi ahyana ba’da ma amatana wa ilaihinnushur.

It means: Thanks and praises to Allah who brought us to life after having given us death and to him we shall have to return.

As a Muslim child, it is a good practice to wake up early and sleep early in the night. Once you are awoke, your face must be washed. The holy prophet Muhammad peace be upon him has taught us many prayers, amont which this is useful for entering the bathroom:

Putting the left foot first in the bathroom is a good practice, then this prayer should be recited:

Allahumma inni a’oodhu bika minal khubthi wal khaba’ith.

It means  O Allah! I seek refuge with you from the bad and evil things.

The children should have bathroom manners, they should not talk in the bathroom and sing songs. They should also come out of the room with their right foot out first.The following supplication is recommended for coming out:
Ghufranaka. Alhamdu lillahilladhi adhaba anniladha wa’afani.

It means I ask for your forgiveness. Thanks and praises to Allah who removed from me
the  suffering and gave me relief.

Washing the hands three times and rinsing mouth three times is also a good practive. Rinsing should be done with the right hand. Then rinse your nose three times with the left hand and also wash your face three times.
