Missing amma

Yesterday Daph went to groceries leaving C and myself at home. C was sleeping when Daph left and so was not aware of amma's absence when she woke up. Surprisingly she didnt cry. I started playing with her and later she played some music. She didnt show any signs of missing amma. However, when amma returned after an hour or so, C ran towards her calling "amma!", etc. That was nice.
