I see that I'm not the only one who had the idea to make a quilt for when he's past the baby stage. The baby quilt might have a limited lifespan but a bigger quilt could be dragged around for many years, even into adulthood!
As someone who lives in a colder region, I can use many, many quilts before it becomes "too many" but I'm sure this is something that varies from person to person. I've been known to use three at once just for myself!
If you think you'll get an honest answer (some people might say yes "just to be polite"), you can just ask.
