Sona Sharma, very best big sister?
(Book)

"Sona Sharma's house is full of people who joke often and argue sometimes. Relatives come unannounced, the phone rings frequently and friends drop in all the time. Then one day Amma tells Sona she is going to have a baby. Is that good? Sona isn't sure -- she has always enjoyed being an only child -- and straight away she has a word with her best friend, Elephant. When Sona learns that there will be a baby naming ceremony, she is determined to find the perfect name for her new brother or sister. Because although she realizes that her life is about to change, and while she's having some difficulty in coming to terms with having to share everything with the new baby -- including Amma and Appa, her grandparents and her home -- Sona Sharma wants to be the very best big sister she can be."--Jacket flap.
