Ds1 and I have time together when dd is asleep - either nap time or after she goes to bed at night. Lately dh, ds1 and I have been playing uno at night times, which he really loves. Or we read a couple chapters of our latest book together.
Dd is very domineering and gets a lot of my attention every day so I don't need to consciously make time for her.
Ds2 is only 10 weeks and demand fed so he is with me all the time, too.
