Don’t know if this will help, but….
We pray frequently throughout the day (at meals with Dad, as well). We always pray before we read our Character stories (Missionary and the Millers right now) and at their request I pick a number between 1 and 10. And, I prefer to say to my kids, “Let’s give thanks to God for our day.” I’m hoping that will ‘prompt’ thanking Him first for His love, mercy, forgiveness, etc. Also, I try to ‘talk’ to God when I pray aloud so I don’t sound like I’m trying to be so mature and spiritual:) Anyway, the one that is closest prays. My kids are big on prayer requests (like they hear at church service) so they ask each of us for a prayer request or praise (my 8yo will call on us like at church, “Br. So ‘n So, do you have a prayer request or praise?” Then we share. Usually it is a long list of those we know are unsaved, sick, homeless, missionary families, and that their dad comes home safe from work, etc. I also try to say, “Let’s give thanks for our food,” instead of let’s pray for our food. Our food doesn’t need to be prayed for does it?? IDK, maybe I’m wrong:)
Since you asked this question Lindsey, it gave me a chance to make sure the my 8yo and 5yo knew that they can tell God anything. So, while we were playing War, I asked them. My 5yo was certain we could because He is our Savior and our Father, my 8yo thought it was a trick question (he’s a perfectionist and doesn’t like to be wrong). I whispered to him that He knows everything anyway. I explained that He wants you to tell Him everything….if you are sad, happy, scared, frustrated, thankful, etc….just like your mom and dad wants you to. I also explained that if you can’t tell us (for whatever reason) you can always tell God. I know as a child that I did not feel comfortable talking to my parents, but I knew that I could talk to God. Sometimes He was the only one I had to talk to, so I am thankful that at some point someone (maybe my mom) told me I could.
I’m so thankful for the questions that are asked on this site. They encourage me so much and prompt so many good discussions with my own kids:)
