I have three kids....
once a week for each of them; i take on an outing...to the store or the movie; mall time; library; swimming..etc..some kind of activity....
I make it 'our time' for each one...it's hard to fit them all in during the day when chores meals bedtime wakeup time school is there every day..so i try to make them feel special with just time alone...on weekends we do things as a family...whether it's a walk to the park; a picnic...read together..go to the movies..etc...my kids tell everyone who listens...that they are loved and special....
I love hearing that and seeing the smile on their faces....
(Also; no guilt involved when it's 'me time'...**wink** )
