It gets better. When my kids were small, I did not do side projects or have hobbies, or learn anything new outside of work. I did start to have more free time after they no longer were toddlers. That period of time was almost 10 years from the first child until they all are were 5+ years old, but that is now past history. Now, my learning, hobbies and projects have recovered. Some day, it will be history for you, too.
