14 month old is an awful sleeper!

Ca

My son turned 14 months on August 29th and is an awful sleeper. I think he slept better when he was a newborn! We've always coslept and he's done well with it. A couple months ago we would nurse then I would lay down with him and pat his back till he would fall asleep. Then he started to where we would nurse laying down and he would get done, crawl away, and fall asleep. Now we're nursing laying down, but he will not fall asleep by himself. I'm usually in there every night for at least 30 minutes patting his back and holding his butt down because he just wants to get up and crawl around the bed. I've tried putting him to bed earlier and I've tried putting him to bed later. Nothing I do helps and I'm at my wit's end. 😔 I don't get any time to myself or to hang out with my husband because he has to go to bed since he works the next day and it's starting to take a toll on our relationship. Any help or advice would be greatly appreciated! ❤️
