P.S.
Dear J.,
Growth is also genetic, don't panic. My family is tall and stocky and my two children grew at a fast pace. Be thankful that she is sleeping all night. This is a good start and don't interupt it because this will set the pattern for the rest of her life. My daughter is now 21 and she is in college and goes to bed early to be rested for school. Good sleeping habits are good. As far as the feedings are concerned don't panic. If you are feeding on demand, she will eat when ready. Are you supplementing her breast feedings with cereal or fruit? This is what will make the difference. Some children are content and happy. Don't worry be grateful you have a happy healthy baby who is not fussy.
