Toddler play

This weekend I was able to observe my daughter Emily (22 months old) and my niece Amelia (26 months old) interact. This is the third time they've met, but the first time they played together. When Emily was 3 weeks old, she didn't even notice 3 month old Amelia. When they were both around 1, still not interested in each other. I use the term "play together" lightly, because just like all the books say - toddlers really don't play "together," they simply play "near" each other.
