I've almost hit my goal of 6 months. We are at 4.5. We have had to supplement with donor milk from my sister when it came to daycare. I can feed him enough but it's a combination of not having much extra after he eats as well as not responding to a pump. It took a team. The Thompson team plus a local lactation nurse, who was impressed that even with a tongue snd lip tied I didn't have pain. My doctor worrying about his size as it took 5 weeks for him to regain birth weight, but then remembered his sister, who was on formula, gained slowly and was only 2# bigger by this age. We also found my old measurements and the little guy matched my weights exactly. This pulled pressure off as it looks small sizes are hereditary on my family. He had issues keeping food down which lead to adding to his small size. That got taken care of but thanks to the group I held my ground with not supplementing formula (until 3 months when he stopped sleeping through the night after sleeping through since 5 weeks and that is adding one scoop into an extra 2 oz of breast milk after he eats from me) and not supplementing a lot of breast milk until daycare.
