Explain baptism and first communion to a child

[Glenshee]

We are going to DD's friend's first communion soon and my DD (7) has already started asking questions. I think she will be considering whether she'd like to be baptized and take communion herself, so I would like to be able to explain what this would mean for her. She wasn't baptized as a baby because in our family we all believe in different things and we wanted her to make up her own mind when she's older (which she clearly has).

Thanks!

Baptism- being welcomed into the family of God.

Communion- receiving the body of Christ to allow us to feel closer to him whilst here on earth. ( I am RC so appreciate there will be other interpretations of communion). Sometimes children will refer to it as meeting with Jesus in communion.

Thanks Spinaroo!
