Thanks for the info everyone

Yes it was advised by a nurse that if we ever want her to take a bottle in the future we should start introducing a bottle at 3 weeks of age because they are used to breastfeeding and have the technique down but after 3 weeks they can become set in their ways and it can sometimes take months to get a baby to take a bottle if you wait too long. BUT she was supplemented in the NICU with pumped milk when I wasn't there to nurse her. But she had no issues taking to a bottle at all... she will eat from anything... even the dogs nose lol.

I have decided to start pumping again. My supply of pumped milk from when she was in the NICU is starting to run low and I do still want to use a bottle for her last evening feeding.... ONE: because I at least KNOW for sure she is getting as much as she needs at least once a day (I am always concerned she is not taking enough from me) TWO: because she falls asleep on the boob during her last evening feeding and it takes a couple hours to get her to eat enough that she will go to sleep satisfied AND I don't want her to get used to needing to be breastfed until she falls asleep because later on that will be a hard habit to break her of. So as of right now I bottle feed her her last feeding, burp her, change her and put her in her crib with her pacifier. But I have heard of babies getting used to falling asleep for the night while nursing and then they can't be put to bed any other way later on. and she has become pretty good at the routine we have now. THREE: like husky_mom mentioned.... it's also nice sometimes for dad to get to do the last evening feeding. He doesn't get to feed her much and I think this helps them bond more and it gives me a nice little break.

But I think I am just going to continue to pump and save that for bottle feedings when needed.... that should also help keep my milk supply up or even increase it if I do it enough. BUT I also might try giving her some formula every once in a while so she gest used to it in case she needs to be on formula for any reason then it won't be a shock to her as she will have already had it and might be a little more open to taking it.
