I can understand your having a hard time finding time and energy to do things, when you have two little persons dependent on you, plus the other responsibilities you have. BUT - there are 24 hours in everyone’s day, no more no less. You need to carve out some of that time for prayer - for your sake, and for your daughters’ sakes. They will depend on you to lead them to Christ, as they grow.
I suggest you focus on fitting in the prayer of meditation, whenever you can and wherever you can, during the day and during the night. For example, using the prayer the Our Father, which I assume you know by heart, you can resolve to prayerfully ponder one particular phrase or petition of that prayer, every free moment you can find during the day, And the next day, focus on another phrase or petition of that prayer. There is the intro to the prayer, and 7 petitions. In 8 days, then, you could make your way to complete the prayer with focus upon every part of that prayer.
By the prayer of meditation, I mean prayerfully ponder, listen intently to, listen for the meaning of, and deeply embrace all that you hear from the Lord, as you speak to Him those precious God-given words of prayer. If you begin with the intro to the prayer,
“Our Father, who art in heaven,”
there is MUCH to listen to, in those words:
“Our” - not “My”, not just “Father” - but “Our”. Why does God want me to say “Our”? Why is that important to God, that I include everyone in the “Our”, and not just myself? So I ponder this part of the prayer - and I PRAY it. I say it, slowly, many times during the day, as time allows, and I ponder it. Realizing that Jesus said to say this, I SAY it. Realizing Jesus said to pray this, I PRAY it, trusting that the “Our” is good and true for me to say and to mean. Jesus wants me to pray for and with everyone who can say “Our Father” - There is a real and important “Our” - a “We” - a community of believers - a family of believers gather together in Him, in our one Lord and God - Our Father.
If you dedicate every day to such meditation upon, and praying, that beautiful and “perfect” prayer the Our Father - the prayer given to us to pray by God Himself! - then I guarantee you will grow in prayer.
