Here's what I've discovered in the last few months. Walking foot is heaven sent (don't know how I lived without it). But, even with the walking foot I find SID very difficult.
FMQ is a scary thing but once you get started it's so much fun and the quilting process goes so fast. I practiced on a couple layers of paper towels so I wouldn't use up fabric I would need later. I had a blast. Now, that's not to say I'm really good at it but like most things I think I can't only get better with practice. I did purchase a FMQ foot from Amazon for my machine. Was only a few dollars and well worth it. Just quilt loosely so the baby quilt will be soft. Have fun either way.
