Re: 9mo eating solids, asked to supplement with formula
I think your pediatrician is being overcautious. According to this weight-for-age chart for breastfed baby girls, your baby is between the 50th and 25th percentiles for weight, which is in no way underweight. (Healthy children come in all shapes and sizes, and not every child can or should be in the higher percentiles for weight!)
I do not think you should follow your pediatrician's advice. Perhaps you need a new pediatrician who gives better advice? I know mine would say "Your baby's fine, until the first birthday solids are just for experimenting with new tastes, textures, and motor skills. After the first birthday, the transition to a majority-solids diet may be a gradual one."
Since you're going back to work, and you haven't had good luck with the pump, I would suggest:
1. Consider getting a new pump- some moms need a better pump in order to get good output.
2. When you are with your baby, nurse more often, not less. Breastmilk is more calorie-rich than most solids.
3. Concentrate on high-calorie solids at meals if you are still worried about weight gain- whole-milk yogurt and avocado are good.
4. If a new pump does not enable you to leave breastmilk bottles, consider leaving bottles of formula when at work. Under the age of 1, milk or formula should be the baby's primary source of nutrition, so formula is a better choice than solids.
