I feel for you hun. Have a look at Cole your child's sleep problems by Richard ferber. It's the ferber method I used with my first and he's been sleep trained since he was very young. I use a variation of that with my 2nd as he's been a bit more spoilt. I only started a week ago with him, but honestly if it's going to work you'll see it in a week and already he's either sleeping through or waking for 1 feed. The variation I use is that I stay in the room next to his cot singing till he puts himself to sleep. It's about teaching then to comfort themselves to sleep. So you have to be mentally strong enough to listen to lots of crying and screaming. There are many other methods, no cry, gentle methods if yiu search online, but I believe this way for me personally to be the most effective. The first day both my kids cried for like 50 minutes, you're obviously comforting then here and there but you're not putting them to sleep, you just keep going till they finally fall asleep. By the next night it drastically drops to 20 mins for my first and 10 for my second. It really works. And as he's gotten older because he knows the skill of comforting himself to sleep, it's meant at Nap times I can go let's go and just sit by him and he'll go to sleep, I still breastfeed my 1st so I feed him both nap and night times but if he wakes in the night, I have a rule, if its before 4am then no feed, and if its after he'll get food and settled back to sleep. Anyway, here's the link to the book x

Iv sleep trained both my babies they both sleep from 19:00 till 8:00 every night have have done since 6 weeks old routine is key bed at the same time every night same routine over and over again I'd feed her just before you want her bedtime to be then put her in bed in her own room and walk away iv let both mine cry it out and it really does work its not nice but you'll get sick I'd you don't have your sleep and some time to your self if she wakes in the night feed her again soon as shes done feeding and not just using you as a dummy put her straight back in her room xx @denbydee

My son went through a stage of waking up for hours at a night to play as well. It’s hard but it does pass. Everything is so new and exciting for them they don’t want to waste time on sleep. Download the wonder weeks app, it will tell you all about leaps, so you know what to expect. I put my son in his own room about 7 weeks ago and he’s much better. He generally wakes for a feed about 1am which isn’t ideal but a whole lot better than it was. I thought putting him in his own room would be a nightmare but he took to it so well. No crying it out or anything like that, so I think I was probably the cause of him waking up so often. If he could see me he wanted the boob but now he can’t so he’ll generally just settle himself back down.

My little boy breastfed to sleep until he was 17 months. I ended up co-sleeping with him from 4months until 8months where I just couldn’t take it anymore! Moved him into his own room and fed him to sleep in a chair then down in cot and he woke 2-3 times a night which was a blessing in disguise! About 10 months I did so controlled crying but not fully! I fed him and when he was drowsy, put him down, went back in the room every 30 seconds to soothe him and by night three he would go down wide awake and put himself to sleep. He is now almost 20 months and was the same we say ni night at 6.30 he laughs and runs up to bed goes in his cot and wakes at 6-7am, this week he has been unwell so it’s been a bit different. Also I know not everyone agrees with controlled crying but it worked for us and he never gave out a fully distressed cry more of a mumble as he knew I would come back
