First, let me say I nursed my daughter to 12 months and am eager to do the same for my son. I have returned to work and cannot keep up with his appetite through pumping breast milk alone. While I wish I could maintain the milk supply, I realize I need to supplement a couple feedings a day with a formula (the dreaded 7-letter word!). Please don't admonish my decision. I've already given myself permission to supplement and am looking for advice on possible supplementary formulas. Thank you in advance for your help. This community of moms is just fantastic.
