I gave E a new treasure basket this week. It's filled with coral that her grandmother brought over for E and O, and she loves it! I watch her carefully since she puts everything in her mouth. I don't like for her to gnaw on the coral, but I let her put it in her mouth to experience the taste and texture (and I even tried it myself to make sure that the coral wasn't too abrasive for her tender gums).
I love to watch my girls play with natural objects, such as rocks, shells, and coral, and it's nice to know that they actually prefer these things to junky plastic toys (usually!). I love how E has her sweet feet propped on the basket as she explores the coral!
