Leasha, I night feed DS until he was 9months old or thereabouts, i stopped becasue he began waking 6-7 times a night and i was back at andjust couldn't function on that much sleep, but until then i was happy to night feed, in the end i had to stop cosleeping as well because i felt like it was too much temptation for DS to wake and smell me but not have me IYKWIM. We had about a week of rough nights while i changed the routine now he pretty much sleeps through from 9pm till 6am maybe waking once for a quick re wrap and dummy. i was determined just like you sound, no formula, no crying it out no matter how many people told me to, it just wasn't right for me/us.
You'll know when you're both ready to stop night feeding and then you'll feel better making the decision, until then just keep doing the great job that it sounds like you're doing.xxx
