Onsies

Am I the only one that puts a onsie on their baby everyday as an undershirt? I've dressed all three of my kids this way especially since they were all tiny during the winter months. My friend who has a baby a few months older than mine told me I was crazy for doing this. Of coarse during the summer months I won't be layering her outfits but I now I'm curious to see if anyone else does this!!!
