So, I've had a really rough breastfeeding journey that I won't really go into, but suffice it to say that my 7 month old has not willingly latched or nursed since she was about 2 months old, and I've been pumping and bottle feeding since then. I've been trying everything to get her back to the breast, and nothing has worked. Well, last night, I tried this odd-looking thing, and she nursed for a few minutes, which for us is HUGE. She didn't seem to fully understand it, and after a few minutes, she started wanting to yank the thing off my boob and suck it like a bottle, BUT... for a few moments, she triggered a letdown, she was getting milk straight from my boob, and it was SOMETHING. Which, after 5 months of NOTHING was a big deal to me. She may never do it again, or I may be able to gradually leverage it into something more habitual, but either way, it gave me those moments, and that's enough for me to give it a 5 star review. So, take that for what it's worth, but if you've tried everything else and want something else to try, this might be worth it.
