Thanks apeydef. We are still chugging along EBF but I continue to whittle down my freezer supply. I think when I posted before he was going through a growth spurt, so I'm not going through the stash quite as quickly. I am probably going to make it another week or two and I didn't think that would be the case. I am usually able to pump at least twice, sometimes three times at work, but sometimes he takes four bottles at daycare. Depends on the day. And that last pump at work is a tough call - if I do it, then sometimes I'm off his schedule when he gets home from daycare with DW, and I'm not full enough yet to satisfy him the next time he is hungry. It is emotional. Which is why I continue to plan for the day that supplementing may be a reality, just in case. I found a formula I like and bought it early so that I wasn't leaving it to a last minute emotional purchase. I'm thinking we should try it for the first time at home so that we can see for ourselves how he reacts, rather than letting that happen at daycare.
I continue to be interested in any advice from moms who have btdt with supplementing.
