I get alot of this and have developed a thick skin. We have 9 children and are hoping to have more. My SIL has zero. My BIL has 2. To each his own. I don't give people a hard time for having none, 1, 2, etc so whatever. I don't care what people think about me or say. Our neighbors have 1 or 2 kids (or none) and live in houses bigger than ours and drive hummers. We have maybe one garbage can out on garbage day and four recycling containers. Our neighbors have at least 2 or 3 garbages and usually no recycling. We use cloth and always have for diapers. We are very earth friendly and our (grown) children are as well (our younger kids are too, of course, but they live here so it's different). Listen to your heart. That's all that really matters. My MIL hasn't spoken to us in two years b/c we have chosen to have a large family. Really? How is *that* accepting of everyone or loving? It's not. It's just ridiculous. We have tried to be kind and do kind things for her. She hates us b/c of our family size. That's a shame but we pray for her daily. I hope her heart changes one day.
We only have one child right now and don't want quite that many kids, but I know what you mean about the garbage situation. We use cloth and reusable whenever possible. Our neighbors have a FULL and overflowing garbage bin days before trash day (and they never have any recycling) and they don't have any kids. Ours is usually only half full and our recycling is full. Your ecological footprint is not based on how many kids you have- it's the choices you make and the choices you teach your children to make that make a difference.
