Who am I ?

Everyday is a milestone to my girls. I like to play " identify " with them. I will always ask them " Who is daddy? " and they will either show the " dont have " hand action when daddy is not at home or point to our wedding collage and daddy if he is at home. They can acknowledge mah mah (my mother), gong gong, mummy, ye ye, ma ma (my in-law), ah yi and ka ka (my maid). One day I asked Clarabelle " Who is Clarabelle? " and to my surprised, she pointed herself. Then " Who is Abella? " and she pointed Abella. I tried on Abella and when asked " Where is Clarabelle? ", she pointed to Clarabelle and said " Bel ". When I asked her " Abella lei? ", her petit index was pointing her chest.
Now, I am still very puzzle why they are not oblige to call mummy? They will walk to my hubby out of no reason and call "daddy" or my mother " mah ". When see my maid they will call " ka ka ". I hardly see them approach me and call mummy, not even when they need my attention where I am at the upper hand. When I prompt them to call mummy, Clara still say "daddy" and Abella sometime " ma ni" sound like barney...
Mummy feel very jealous...mummy is always accompany you both yet mummy dont have the privilege from you both :(
Must be they always see me, sien already... Babies, cannot take mummy for granted hor!
