If you have never tried Acorn slippers for your little one your missing out.  I was given a pair of Acorns when my daughter was about 12 months old and she and I both loved them.  They are super comfy, easy to put on and take off, warm enough for So. Cal. and washable in cold water.  Needless to say Sofia is now 31 months old and her feet keep growing and I always make sure she has a comfy pair of  Acorn slippers to put on after her nightly bath.  They do have leather soles so they are intended for indoors but are ok for short outside time.  I highly recommend.
