Sleep training

Hey Everyone! So I’m in the middle of sleep training my 6 month old, it’s not that easy but I’m being patient, I started reading the Ferber method an most likely stick to that method, only thing is my baby wakes up atleast 10-15 times at night to find comfort an that is nursing, he’s not hungry he just wants to nurse, he doesn’t even stay awake he just fusses an wants me to soothe by nursing an it’s getting tiring! I need advice an tips! 1. I wanna stop nursing but don’t know how. 2. Do I just let him soothe himself back to bed? I can’t really let him cry for long cuz my husband has to be up at 6am for work!

Thank you
