There isn't really a "goal" for solids amounts, so to speak. Your best indicator is to keep an eye on her bf or bottle intake, since those are still her main sources of nutrition. Her portion sizes may increase a bit over the next few weeks, possibly up to 4 tablespoons or so, but only if she's still getting the right amounts of breastmilk or formula. It can be hard to balance it just right, and it often changes from day to day! HTH!
