I would suggest an early rise, while all are sleeping. I was just noting to my wife this morning how 4-4:30 AM is a beautiful time of quiet: no cars, no lawn mowers, no children...and this is when typically the birds begin to sing and the wind blowing through the trees is audible.
I just returned myself from my first St. Ignatius retreat (what a blessing!) and it was suggested that I strive for at least ten minutes a day in meditation.
I would avoid using the Ignacian Spirituality site for information.
I hope this helps, and either way make the commitment to it regardless. Perhaps asking our holy mother for the grace of just a few minutes would also help.
