Not that I know of, but if you teach your kids religion regularly (like out of the Baltimore Catechism and/or the Faith and Life series), you can find lots of opportunities to insert apologetics points into the lesson.
For example, when teaching about the Communion of Saints or the Immaculate Conception, you can bring up the fact that many Christians have objections to the Catholic understanding of these doctrines. Explain gently (and without rancor to the opposing view) why and how the Catholic understanding is logical, historical, and biblical and, as appropriate, point them to the places in Scripture that support the Catholic view.
The same thing when you are reading Scripture together with them. If you come across a passage that has some apologetics connection (for example next Sunday’s Gospel about the wedding at Cana where Mary tells the servants to do whatever Jesus tells them to do), take the time to point it out and explain it’s implications at a level appropriate to their understanding.
