Your baby may as well get some studying done while doing his or her tummy time. Both of these numbers rugs are marketed to adults so this may be a case of nursery design trickling out to all corners of the home.

The Urban Outfitters Numbers Rug is reminiscent of Binth's Numbers Poster in a more subdued color palette. The cotton rug measures 36" x 60" and is inexpensive at $28.

The West Elm version is more expensive, but it's also much more luxurious. The wool rug is sold out in a few sizes, but is still available in 3' x 5' ($109), 5' x 8' ($279) and 8' x 10' ($549).
