Breastfeeding

Been really thinking about weaning Son off breastfeeding but I honestly don’t know if it will make a difference he’s about 14 months still breastfeeds like he was 3 months old he doesn’t sleep through the night either so I’m nervous I’m going to be up all night long if I pull boob away … need ideas or thoughts he’s still up all night long he will go to bed about 8 wake at 10 back down 5 minutes later back up at 1 he takes sometimes about half hour from there to doze completely off back up at 3 back to sleep then up at 6 then it depends on him if he’s up sometimes he will sleep till 8 after that each time he feeds I’m exhausted but I’m worried if I pull boob I’m never going to sleep I’ve tried everything to get him to sleep cereals, keeping him awake, letting him nap to he’s not “over tired” , bananas they say helps you sleep idk, dr told me his low iron could be the cause so he’s on iron he sleeps less then before , warm baths routines lavender white noise nothing at all works … last thing would be to pull breastfeeding and pray he learns to comfort or self soothe im not letting him scream I tried it a couple times it doesn’t work with him he don’t let up He don’t take pacifier anyone ever experience a stubborn one like this he’s definitely not ready to stop breastfeeding he’s showed me nothing that says I’m done and I want him to be fully ready but idk if pulling it would get him to actually sleep 🤷‍♀️
