SPEECH: She has not started talking yet but makes lot of sounds like Aye, aaa, hooo, hee, nana, baba, bubu, etc. But has not said any word yet. Makes these sounds on her own. She does not usually use them to communicate with us. She generally uses gestures to communicate. She will either bring us the thing that she wants or will take us by hand to the thing she wants. For example, if she wants snacks, she will take me to the pantry, take my hand and put it on the handle and make some sounds like umumumum. When I open the pantry she tries to bring the snack box out and takes her snack bowl as well for me to put them in.

She loves music and will clap or dance etc. She can point with index finger. She does not have any abnormal tantrums and is generally a very calm, obedient, and quiet child.
