One-on-one Time.

Dont give her a choice next time. J. say you and I are going out.
I agree with S.H. it doesnt have to be a formal outing or dinner
think of what she would like to do. Maybe a play place she would love, getting her hair and nails down, going to the park with J. you, taking a hike, playing in the yard, maybe watching a movie and cuddling? you could take a train ride or go to a museum or the zoo..the possbilities are endless

Dinner sounds to formal for a kid. when she gets older dinner and talking would be good but at 6 J. do what she likes and enjoy it together

My 5 year old has wanted the same thing. I try to come up with something every now and then but not always planned. Weekends are a good time while the little one naps. We go on a bike ride and walk down to the creek and throw sticks in. He asked my husband to go to the driving range one day so they went. Be more casual and do something she gets to pick. And remember kids are funny...one minute they are all about mom and the next minute all they want is dad! LOL!

Next time I wouldn't give her the choice... Just say "Hey, get your coat on. We are going to go out to eat, just me and you."

If you give her the choice of you or daddy and she chooses daddy but then you turn around and make her go with you... That would be defeating the purpose. But if you just tell her that she is going to go with you without giving her the option of daddy... It's fine :)

No, ask her what she DOES want to do with you, and do that.

One on one time in our house is never anything formal. It'll be my husband is going to run out and get the mail from the PO Box and maybe pick something up for dinner on his way home and he'll take one of our three along. Or it'll be me running into Target while my husband sits in the car with the sleeping youngest and one other will stay in the car and I'll just take one of them in with me to grab the things we need.
One of us will read a book with one of them while the other 2 are playing somewhere else in the house. Or watching a show on TV with one of them that the other two don't have interest in.
We've never taken the kids out just one on one for a formal dinner at a restaurant, heck even my husband and I don't do that.
Don't stress about making it all scheduled. It doesn't need to be.

Why are you asking her? Plan something you know she will like and say "it's time to go." Or again without asking, tell her the two of you will be spending time together in however many days, then you can make a list together of what you might do. Or have her write down activities on little slips of paper and when it is time (a day or two ahead for planning purposes) have her pick one out and that is what you do, either with mom or dad depending on whose turn it is.

..... one on one time... does NOT mean... you have to go out, or take her out.
One on one time, is just that.
It can be, anywhere in the home doing anything. WHICH the child, enjoys. Even if that means, laying out on a blanket looking up at the sky, in your own yard. And doing it only with that child.

I have 2 kids. 4 years apart.
I do one on one time with them, any ol' time, whenever.
It is not a formal... outing. Or it could be.
It could cost money, or it could be free time.

But I ALSO TEACH MY KIDS... that everyone needs, alone time.
They just have to say it.
To each other, or to us.
The 2 kids.... or any kid for that matter... does NOT have to... always be playing together nor be in each other's face, all the time.

Do you work or are you at home with her every day? If you are home, it could be that she chose daddy because she is with you during the day and doesn't see daddy as much.

I agree with others and don't give her the choice. One time, daddy can just take her and the next time you take her.

We've done it both ways in my house. Sometimes it's a special event where my husband takes one and I am with the other. Other times, it's just a quick errand with one while the other stays at home with daddy.

And even if we are all at home, we've split up when they both don't want to do the same thing and they get some one on one time that way. However, that's not a guarantee since the other may decide to join in at any time.

I would reframe the question to her. "I'm so excited that it's our turn to spend time together. What do you want to do?" Let her choose. You might help her by offering choices but see what she comes up with on her own.

Hi, Mama:

One-on-one time needs to be everyday.

It doesn't mean going out.

Good luck.
D.

Take her someplace that she loves. Tell daddy to say he doesn't want to go there so when you offer that as a choice to go to she has no other way to get there.

Once you two start rebuilding that relationship you'll see a difference.

Next time don't give her the choice just take her with you.

One on one does not necessarily mean out for dinner. Just having her with you running errands can be fun. How about just making cookies together. There are so many ways to achieve one on one time.

When my daughter was younger, I made a "date" with her where we got all dressed up went to the movie matinee and out for a sundae. She still talks about it.

Just do something that you two can both enjoy. If it is going skating then that is what it is. Don't over think it, just do it.

Have fun and enjoy the moment. Take a few pictures for memories.

the other S.

I would pick another one on one activity that she enjoys.

You might also look for opportunities at home. When the younger one is napping, do a craft with her. Read books. Play with her stuffed animals. Sometimes my DD wants Daddy because she's home with me and sees me more. And rather than "do you want to go to..." try "DD, get your shoes on. We're going on an adventure!" or something. Sometimes my DD doesn't want to get ready but once we are out, she'll say, "Aw, don't we have anywhere else to go?" when I say it's time to head home. It's just errands, but she likes the time to herself.

I would just switch up what you do with her. Like others suggested, it doesn't have to be going out somewhere. You could do each other's nails at home; make cookies, cake or cupcakes, do an art project, teach her to sew. Let daddy take lil sis out and you and big sis stay home. That way she doesn't have a choice.
