Breastfeeding and sleep training- help!

Elizabeth

So we initially sleep trained our son around 5 months or so. We did CIO. it was hard, but he caught on quick and started sleeping better. There was even about 3 weeks he slept through the night (12 hours) without waking once most nights. And then sickness and teething happened.

And now. He wakes every two hours again, with the odd random night he’ll go maybe 4-5 hours his first stretch then 2-3 after that. I just go in and nurse him when he wakes up. I have let him CIO during the night ONCE and he fell asleep within 15-20 min (mostly whining, not crying) so I know he can put himself back to sleep... But during the night when he wakes I feel like he’s hungry and needs to nurse. But at the same time I know he can go 6-10 hours at night without eating and be fine. When I nurse him back to sleep he’s suuuuper easy to put down, right back asleep. He doesn’t fight bedtime. He’s really an easy baby, I’m just trying to figure out how to get him sleeping longer at night!

What do you mommys do? I need help. Do you nurse them once and let them fall asleep on their own the rest of the time or not feed them at all?
