Jemima vs mumma

Little g still doesn't really call me mumma. She knows how to say it, but doesn't. We went to the Playschool concert and I bought G a Jemima doll $30, ABC once again taking all my money! She loves Jemima. She calls Jemima by her name all the time, but still no mumma! We are currently in New York and Jemima joined us on our travels, and we went to the biggest ToysRUs in the world in Times Square and got I Love NY monkey to keep Jemima company lol.
