My DS is developing normally, into everything, running around a complete chaotic delight- says a few words such as Do Do (dummy) Bubble, Tickle, No (of course) Grandad, the name of his best friend etc etc Absolutley loves his Dadda who is at home with him 3 days a week whilst I work. Says Dadda all the blimin time though and never says Mummy, just to rub it in he even says the name of the dog! I'm not sure if he just calls both of us Dadda, everytime he does I say Mumma and smile at him and he just smiles back and says Dadda. Anyone else had this or is it just me?
