I think your quilts are wonderful! It is great to have a baby quilt that is "too big" (ha no such thing!). It can be a wonderful place to play on the floor with toys or outside on the grass.
When I made my daughter's quilts I would make a few extra blocks and create a matching baby doll version. This size is actually perfect for a lap quilt when they are in the car seat and still tiny as it can be tucked in and then I would put another blanket over her. Now that she is older they look sweet in her baby doll cradle.
