Wacky and sporadic sleep pattern

Ugh you guys,

My baby is 6 months, just recently started to wake up at different hours every night. One night he wakes up 12 am, 5 am, and wake up time, and then last night he woke up literally at 11am, 1:50 am (WHY!?) and 530 am! I'm so tired from waking up here and there.

I'm EBF, and know that he doesn't really need to eat in the middle of the night. How can I stop that? Waking up once would be ok, but 3?! And every 3 hours it's exhausting!

Anyone else in the same boat? Any other people EBF and want to stop night feeds?
