The Rested Parent-Gentle Sleep Training

My baby boy who turned 19 months on 8/4 refuses to sleep on his own or through the night. He has never been a strong sleeper, but the past few weeks have been worse. He takes an hour + to even get to sleep and is waking up at 11-12 almost every single night. I have a toddler who is also a very difficult sleeper and am struggling to keep up. Any programs/tips/courses/schedules would be very much appreciated! I am slightly desperate and trying very hard ❤️

I've been bed sharing with my baby since she outgrew the basinnet, but even then I'd take her the 2nd half of the night into the bed with me. She keeps waking too many times a night for me to handle. Last night she woke 14 times, the night before 9 times. Typically she wakes 6-12 times. She is 8 months old and I can't do this anymore. I feel like I'm physically dying. I dread sleep but I crave it. I need this to stop. I want to put her in her pack and play from tomorrow on and sleep train her. Is it possible to sleep train the first night she sleeps away from my bed?

Out of ideas and very very overtired! My 9months old who used to sleep like a champ and sleep through the night is now waking up every night after 3h of being put down and it takes me ages to be able to put her back to sleep in her crib. Breastfeeding her used to work like a charm to soothe her right back to sleep but since nearly a month it is never working.

She falls asleep on her own in her crib for naps and bedtime but for some reason won’t settle back down in the middle of the night on her own anymore or after a night feed anymore.

I tried so many things and I’m out of ideas and so so sooo tired 😩 Any tips or tricks ANYTHING

Picture so that we don’t get lost

My 7 month old does good for naps, I lay her down and she takes her binky and puts her self to sleep. She also does ok after her middle of the night feed, she eats and goes back to bed without issues, I lay her down and walk right out. (Im also mindful of all her awake windows and such) BUT Bed time is a disaster. She’ll fall asleep around 7-7:30 but never sleeps more then 40 min, wakes up and cries until she is held back to sleep, she continues to wake up every 30-40 min until 9-9:30 EVERY NIGHT, then she falls asleep for the night. Help! Anyone have any ideas, what am I doing wrong?!
