As of late, I have tried to take them out to Dinner and she has always wanted to come. I have taken just the 3 boys to the movies and on errands to get away from the house. Daughter is a different story. I have to figure out what I can do with her that she will actually want to do w/ just me.
What are her interests? Talk to her and ask her what she'd like to do without her brothers around. She might just want to play a game w/you, go shopping, out to eat, or go to a movie the boys wouldn't be interested in. She's at an age where she will still want to hang out with you, so take advantage of the bonding time before the teen years hit!
