I have a 17yo, an almost 11yo and a 3yo.

The 17yo is out to college and love to have her brother(11) over for a day or spend an afternoon at the park with the 3yo. 11yo and 3yo are playing well together most of the time; it's just a challenge to homeschool with the 3yo around since she never nap and always want to be a part of what we do.
There were time when it was challenging but I think it's more of a stage in life (teenage) than an age difference

Oh! and many of DD1's toddler clothes are back in style so DD2 gets compliments for her unique look without spending.
