Is the weight loss to do with her eat pattern or is it that she's becoming a lot more active? How is she though, happy, lively, energetic or is she quiet, not much running around or movement, and doesn't really do much activity? These are good clues as too whether she's getting what she needs or not. With the food, definately keep her bf up as much as she wants and maybe introduce other types of solids - finger foods.

Also please don't stress with the eating of solid foods either. It's really not that important that babies have to start eating at 4 or 6 or 9 months. It's really when their little systems are ready not when the chart says. Your little miss will let you know exactly what she needs when she needs it, she will help guide you as to what's best for her little system. The piece of paper couldn't possible explain what's best for your little Charlotte, only she can.

HTH.
