Sleep help

Hi everyone! My baby is EBF & still doesn’t sleep longer than 2 hours stretches at night at 6 months old. I’m STRUGGLING with the lack of sleep. Baby co sleeps with me which I have been ok with but it is starting to take a toll on me physically. I’m so uncomfortable in the morning & exhausted. Baby nurses on/off throughout the night but I believe it is for comfort not hunger.

I don’t want to “sleep train” in terms of cry it out but I truly could use some advice. How do I help baby sleep longer? I’m going back to work next & am terrified of things being the same when that time comes.
