As someone who does not have the prayer life that I feel I should have (though it is getting better, especially the smaller, impromptu prayers, just relying on God throughout the day) I thought this would be a good book to help me to help my children to pray.
With my girls, I have always said a set prayer with them at bedtime from when they were little:
God, Our Father, I've come to say
Thank you for your love today.
Thank you for my family
And all the friends you give to me.
Guard me in the dark of night
And in the morning, send your light. Amen.
DD1 now considers herself an atheist, so doesn't want me praying with her any more.
DD2, otoh, is happy for me to pray this prayer with her, and we have started adding our own prayers at the end of it. Though she often wants me to say the prayers on her behalf, I'm trying to encourage her to talk to God directly.
Personally, I found some of the suggestions to be a bit formulaic (as in 'if you do this, then God will listen'), however, this book is still worth reading (especially if you can get it for free!) because there is lots of encouragement within. Dispersed throughout the text are lots of small prayers for you to say, asking God to help you praying for your children, and at the end, there are some set-prayers that you can use too. When I was growing up, my mum said a prayer with my sister and I before bed, and I can barely remember it now, though I recognise it when I see/hear it. And it was in this book, so that made me smile, too (though it listed two different endings, and I can't remember which it was my mum used to say, but think it was the first one).
Now I lay me down to sleep,
I pray the Lord my soul to keep:
May God guard me through the night
And wake me with the morning light. Amen
or
Now I lay me down to sleep,
I pray the Lord my soul to keep.
If I should die before I wake,
I pray the Lord my soul to take. Amen.
