My kid is in that age range and I'm going through the same thing as you. I wake up at 4AM, walk the dog, get to work before 7 AM (some days as early as 5:30), work until 4 PM, get home at 5 PM, play with kid and eat dinner, get kid ready for bed and read to them, and then I have 30 min - 1 hour before going to bed. By this time I'm exhausted and when I try to do anything technical fall asleep 10 minutes in. Our weekends revolve around my kid 100%. It is rare for me to be doing something besides playing with them or doing errands with them. I'm starting to see some independence though. I really enjoy playing with my kid and it is a wonderful experience, but I've gotten out of shape and there are a lot of things I want to work on but never can. No hobbies right now outside of being a parent.
