My brother and his wife did not sleep train their boy and co-slept with him. They had endless issues with sleep that continued past 2y old, were constantly exhausted, and eventually alternated who slept with him. We sleep trained our boy, same age, had very few issues even from very young.
Children are so different, from so early, it's not at all obvious what outcome for a particular kid is because of different strategies taken and what comes from their individual natures, or other aspects of their environment.
Co-sleeping's known to increase the SIDS risk, so it's another reason people are sometimes reluctant to do it, even if it would make the baby more comfortable.
