I am thrilled that my two year old is interested enough to try to make the sign of the cross! You should have seen him with the holy water font at church a couple of weeks ago ~ he would reach up and dip his hand in the font and then splash his forehead and walk away (rather, do that little toddler stomp away), then come back and do it again and again… boy that just tickles me! He just about bathed in holy water that morning!
I say prayers with him at night before bed as part of his story time. I stick to the Lord’s prayer, the Hail Mary, the Glory be, the Guardian angel prayer, and the night time prayer “now I lay me down to sleep…” Sometimes he can stand all of them, sometimes only the Lord’s prayer. And I don’t force him to really pay attention, I let him play around on the bed and such. I just want him to hear the prayers for now, and be happy while hearing them. I do help him make the sign of the cross before and after we pray, and I tell him “Good job!” when we finish prayers and then start a story.
Mine isn’t talking yet though. I’d be happy that my toddler could even say the name Jesus! That all by itself is a prayer! Pray in front of him, let him see you walk the walk and talk the talk, and everything will fall into place in the future (I think, I hope!). I think if you could somehow make prayer time a time for your child to feel peace and to feel loved, it doesn’t matter what form the prayer takes. They’ll always love prayer if they equate prayer with feeling peace and being loved.
Get a bottle of holy water, let him play with it! Play is learning, so try to make prayer time a sort of play time right now, you’ll get his attention a whole lot easier this way. Does he have his own rosary beads? Big colorful ones? And a good sturdy board book of prayers with pictures? You’re going to have to appeal to him on his level.
God bless you for praying with your son. Your efforts will bear fruit.
