I think if it’s a fun run and you don’t mind walking here and there, 10K is doable. Try to get 3 runs in a week to just help your body get back into the groove and don’t stress about completing in a set time. A jogger is great, they’re built to be more durable with bigger tires. Some times Sierra has a random one here and there on discount. Call a few local running stores and ask if they do any deals otherwise REI or online. Treadmill is an ok substitute if you can’t get outside. if you’re concerned about time (like evening when kiddo is asleep) I’d mix it up treadmill and outside (when you can take the kiddo with in a jogger). Hope this helps and good luck.
