Saw an LC again today and our LO isn't gaining weight like they'd like, though she is over her birth weight. LC suggested supplementing with formula 2 oz at every meal, still trying to give Thalia 20-30 minutes at the boob, and still also pumping to give her breast milk in the bottle (or some combo of these things). Feeling a bit overwhelmed by all this. Who else is trying to do or doing BF and formula at the same time? Tips/perspectives? I don't even know what formula to try; LC gave us Similac samples.
