I've been the one to leave myself and my wants OUT of my prayers and always pray for others. I had to have a counselor tell me it wasn't selfish to pray for myself.
Use the A.C.T.S. method (I believe it's Acknowledge who God is and his authority, Confess your sins, T is Thanksgiving - thanking God for what he's done, going to do, etc. and the S is supplementation, in other words, what else is left - needs, etc. which should INCLUDE others FIRST. The order should be GOD, Others and then Self. If you use this method, you'll include what should be included, NOT forgetting the confession and thanksgiving and who God is, but ALSO others.
I would make an effort to find SOMETHING to pray for others about EVERY time, especially if you're not used to it. That may even be..."Thank you, God, for giving Alison the gift of being a kind, caring friend. Help her to continue to be kind and caring to others as you want us to do. Help me to do more of the same."
I would do this EVERY day and then make things like the military, children's hospitals, shelters, food pantries, missions, etc. EXTRA. This is what we do. It helps to remind them DAILY of the needs of others AND then prompts them to WANT to do additional things. I try to expose her to as much as I think her little heart can handle. It's amazing how big the heart of a 7 year old can be when God takes hold of it!
I ALSO make sure to thank God for beautiful days, beautiful sunsets, warm temps, the songs of the birds, the beautiful trees or flowers, the breeze on a hot day, etc. and we ACKNOWLEDGE that God gave those to us. They don't have to be IN a prayer, just an acknowledgement as to where they came from. Children pick up on doing the same when you do them outloud or remind them we need to thank God for the WONDERFUL breeze on such a hot day, etc.
We also talk about it ALLLLL the time in nature...insects, flowers, trees, animals, etc. and how God equips them. LOVE LOVE LOVE those conversations!! And.......I'm sure God does too.
