weaning help

Ashlee
I'm still nursing my 10m old may baby.  I have recently started to try and wean him. I was nursing him every few hours and realized he didn't need to nurse that often. We r eating big boy food
But now he doesn't nurse during the day and he's totally fine. (Usually once in the morning and then before bed) But he's waking up all night long to nurse. I just got him sleeping in the crib and we were going to start sleep training but he got a cold 2 days in. So now I'm nursing him to sleep. Then he wakes up 7-8 times a night. What should I do??
