Starting over

New to MFP, but not new to weight loss. It was easier before, since this time I have a baby, baby weight, and not much time. I have at least 60 lbs to lose and I don't even know where to start. I am so out of shape and working out is not fun anymore. I used to love it when I was in somewhat good shape because I could challenge myself with more intense workouts. I feel like I'm below where I started when I thought I was in bad shape before. This baby did a number on my body, my core is ultra weak. Any advice on where to start or if you have a recommendation for lighter workouts, it would be appreciated.
