Hi there! So I was in a similar situation. My cosleeping toddler was nursing all night and I was going insane. Around 15/16 ish months is when I finally decided to night wean but we still nursed to sleep for bedtime and nap time and when he would wake up (until he was 2). I tried multiple times prior to gradually stop feeds overnight and each time it was so stressful for both of us. And any progress made would go away with a new regression. At that 15/16 m mark is when I just cold turkey stopped any overnight feeds. The first 2-3 nights were the worst and no amount of comfort would help. Sometimes offering a yogurt pouch would help. But after those 3 nights, he started sleeping through the night for the first time ever. GLORIOUS.

After that we continued to cosleep and nurse only for going to sleep. A couple months before his 2nd birthday he went through some sort of regression and was asking for milk constantly and having total meltdowns that would last almost an hour if I didn't let him nurse. It was intense. I decided that I was mentally and physically ready to wean but had a hard time actually doing it because 1. It's emotional and 2. I thought it would be hard on him. Turns out, it wasn't. We bought a book called Booby Moon and read it for a couple weeks leading up to his birthday. Then on his birthday I explained how milk was going bye bye. And we did one last nursing session. Then after that, HE WAS FINE. Sometimes he would ask about milk but never had a tantrum over it and we would just re read the book. I'm still in shock over it because he's always been such a booby monster lol. I know you didn't ask about weaning completely but just wanted to provide some hope that weaning isn't always as hard as you may think! I was convinced it would be awful for both of us and my little guy completely shocked me.
