Life with a young kid can be a huge amount of work!
I've noticed that some people completely give up their hobbies when a baby comes... whereas others continue to maintain their hobbies/interests. What's tricky is when one person maintains their hobbies, while the other person has to give everything up due to lack of time... sometimes happiness can feel like a zero sum game!
What hobbies do you have? How do you and your SO handle balancing your hobbies with the demands of a newborn/toddler?
