Low % on growth chart?

Our girl is 9 weeks, and had a bad case of jaundice for about 1.5weeks after she was born so she lost about a pound. Now she's around 6-7% weight on the chart... Dr doesn't seem concerned, just that she's small and still is gaining weight, growing head/height and meeting developmental milestones. But I'd love her to bump back up to closer to average!!! We exclusively breastfed for 9 weeks but now I'm back at work and pump, nurse at night. Anyone else???
