If there is no other gym within reasonable driving distance, try training at home.
Bodyweight stuff is good to start with. Those Door Gym pullup bars sell for under $30. If you have a little bit more to spend, you can pick up a kettlebell and a TRX. If you the space, maybe get a barbell and some plates.
The advantage of having some equipment at home is that you can fit in a few sets here and there whenever you get the urge and a few minutes of time. After the baby arrives (congratulations BTW), your schedule is only going to get crazier and training will be even harder to schedule.
Getting back your motivation is a sort of self-sustaining cycle, at least for in my experience. Sometimes you have to just force yourself to get started again, but, as soon as you have, your motivation comes charging back full force.
