LLLMeg- If baby seems satisfied after a feeding, I haven't been supplementing with formula. When I'm not supplementing, she seems to want to nurse about every 2 hours. If I do supplement, she is satisfied longer, so I've been pumping if 2 hours have passed. Will this work or should I be doing something else? Generally, its only been one four hour stretch at night after she cluster feeds in the evenings...although the cluster feed usually ends with a formula supplement b/c I'm worried she's not getting enough.
