Perhaps you should try some spelling variations:
"children best and children's playmate" » "children best and children's play", "children best and children's playhouses", "children chest and children's playmate", "children about and children's playmate", "children below and children's playmate"
"children's digest and children's plays" » "children's dignity and children's plays", "children's best and children's plays", "children's first and children's plays", "children's digest and children's play"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("children's digest and children's plays") OR ("children best and children's playmate"))~.
• Removing quotes may allow a broader search: (( children's digest and children's plays ) or ( children best and children's playmate ))~.
• Adding a wildcard symbol may retrieve word variants: (("children's digest and children's plays") or ("children best and children's playmate"))*.
