T.L.
I have two daughters ages 8 and 4. To have one on one time with my 8 year old, I would take half days off of work every once in a while and spend the afternoon with my older daughter while leaving my 4 year old at the daycare. This way, we get alone time together and I don't have to worry about care for my younger one. Doing this also makes my older one feels special. Whenever I did this, she would always ask me why and I'd tell her that's so we can spend time together without her sister interrupting us which she does often.
