Recently, we've starting having Abby pray after Caleb. We want to include her and Caleb started to work on praying about this age, so we figured, why not?
We started out modeling the signs for "Thank you Jesus. Amen." because we figured stringing those three signs together would be plenty for Abby right now. After a day or two, she started mimicking us. Then I started just saying the word and she would sign it. Now, I start her with thank you and she does the rest. She knows that as soon as Caleb prays, it's her turn!
The best part is the huge grin that spreads across her face when it's time for her to pray. Her favorite part is the amen, which is supposed to be a "thumbs up" on the palm of your other hand. Abby's tends to be a huge, excited wave/flail of both hands...which is equally appropriate, given the meaning of amen. :)
Oh, you want to see her praying? Okay!! :)
