I agree with Father’s suggestions! Here are also a few things I do:
-Prayer in the car on the way to work/dropping kids off at the sitter’s/etc. You can either pray to yourself or out loud with the kiddos.

-If you work in an office, you can go to Rosary Army’s website and listen to the audio rosary during lunch or another break. Or, if you have a quiet office, just listen to it w/headphones on as you work!

-I pump breastmilk throughout the day and use those 15-20 mins. for prayer as well!

Hope this helps!

Another way to be creative with prayer—I found Sybil MacBeth’s Praying in Color really invigorated my prayer life.  She also has a version for children.  I keep a private prayer sketchbook, but it is easy to imagine doing this as a family.

Here’s a link:

I find it helps to keep certain prayers posted throughout the house to be prayed during various times of the day—the Morning Offering (prayed before breakfast), Angelus (prayed before lunch), Divine Praises, Anima Christi, Magnificat, Prayer to St. Michael the Archangel (prayed before leaving the house), Heavenly King (prayed before bed), etc.  Sometimes that visual cue can be so helpful during a busy day.  Tying prayers in with the traditional Hours (Matins, Compline, Vespers, etc.) has also been helpful, as is having a specific area set aside in the home for family prayer (family altar, icon wall, etc.).

Something I have done to pray the Rosary on a certain day is to break up the prayers to be scattered throughout the day. So I’ll pray a decade while I fold a load of laundry, then another while I’m cooking, etc. By the end of the day I’ve prayed five decades, and been able to fill my day with prayer.

One way I have found to include prayer in a constantly interrupted life as mom of three very young ones is to print out the lyrics to my favorite hymns and tape them to my kitchen cabinets. They remind me to sing as I cook or wash dishes. I started doing it just because I wanted to learn all the verses of one particular hymn. But I soon found it was a great form of prayer.

I found that getting a Magnificant subscription to very helpful.

The morning and evening prayers are short enough to be doable (very little can’t wait for that length of time) and the books are easy to keep visible so that I don’t forget.

It also helps to tie prayer into something that you WILL be doing. 
The first thing I do when getting up in the morning is start coffee so my morning prayer time is tied to that- normally I start the coffee and start praying before most of the children are up and the day gets busy.

For me (and my mother) I am most successful with daily prayer when I leave a Bible or daily missal in the bathroom and read everytime I use the restroom.  I also tell Bible stories whenever we drive and my children and I really meditate on the stories and imagine the details.

Wonderful, wonderful tips!  I linked to this on my weekly roundup - thanks for sharing, everyone!

I also have four children, four girls to be more specific 7, 5, 3, and 1.  I have always had a hard time making prayer a priority.  I recently started getting up just a half hour early before the girls wake up and have that time with God.  Sometimes it’s a Rosary and a Chaplet, sometimes it’s reading a religious book, sometimes it’s morning prayers to the Holy Spirit, sometimes it’s reading the Bible.  Whatever God lays upon my heart.  I also keep a Christian music worship station on Pandora on my Ipod (docked) and listen to worship music in all that I do.  I try to meet with other women once a week in the morning to pray the Rosary and do the Seven sorrows of Mary.  I pray while taking my kids to school, and we pray as a family at night.  Even my three year old says what she’s thankful for and then any special prayers.  We each take our turn, even my husband and I, first with Praise and Thanksgiving for different things, and then for prayer requests.  We say our Act of contrition together and then pray a decade of the Rosary.  The girls take turns on this.  I’d love to be able to do a whole Rosary (hopefully we’ll get there someday).  Every chance I get a free second, I’ll try to focus on God in some way and talk to him, offering up every bit of stress, or sorrow, every struggle, for the poor souls in purgatory or for a poor sinner.  I’ll spend the day thanking Him for the joys that I experience.  Prayer all of a sudden, through God’s grace has become a huge part of my day.  I hope this helps you in some way and I will pray for you.  It’s so hard to be a good mother when you aren’t being filled up in the Spirit.  May God bless you and your family and all parents, that we may raise children who are driven by God’s Holy presence and purpose.
