Help. Baby won’t sleep and idk what to do

Heather

Hey y’all. My baby is 5 months old. And he has had trouble at bed time since he was a born. We co sleep. Because he had very bad colic when he was a newborn til 4 months old. And he would not goto sleep unless he was right next to me. And it was endless rocking and bouncing and nursing to try and get him to goto sleep. I am a SAHM. So he hasn’t taken naps in his own bed. Cuz again he wouldn’t goto sleep and would just scream. So I’ve had to lay with him at nap times too. Which naps aren’t hard to get him to goto sleep. It’s just at bedtime. I’ve given him baths before bed, feed him, and laid with him. But he just refuses to goto sleep. We start trying to get him to goto sleep at 7pm and end up staying up til 10-11-12am. Rocking him, bouncing him, nursing him. And it’s really taking a toll on me mentally. What should I do? Does anyone have any advice. Should I just put him in his crib and let him cry it out. Or do y’all think he’s too dependent on cosleeping now? Any advice would be greatly appreciated. Im mentally just tapped out. Thanks.
