Homemade, safe baby toys. Encouraging physical developement. Calming and communicating with your new baby. Baby massage. Not much has changed, except the dangers of what materials are now in baby toys, and how to get around that. I found it a valuable addition to my collection of baby books, even if it is an older one. Babies haven't changed, and I was surprised to see that the way we perceive them has shifted. Great ideas from a time when baby learning was coming into its own.
