Weight loss

Ok so I feel like my pregnancy weight loss has been stagnant the last 3-4 weeks. I think I've only lost 1ish lbs since a month ago. My son was born 15 weeks ago and I had hoped to be down about 8 more lbs then I am at this point. I gained nearly 60lbs while pregnant. I've lost 41 lbs. It's cold where I live so taking baby stroller walks are not an option anymore so I do some home resistance workouts a few times a week. I'm starting to get discouraged. Anyone else? I don't want to go to a gym yet because of the germ factor.
