Please help me with baby naps

[HoneyTrees]

7 month old takes all his naps in the sling. Lately my back has been hurting, but gotten a lot worse over the past couple days. I’ve had to take pain killers because it’s unbearable.
I’m not sure how to get him to nap without being in the sling.
I’ve tried before but it just doesn’t work :((

How have you tried before? How many weeks did you try for?

At this stage you're looking to break the sling associations by sleep training. It's gruelling work, but it's worth it.

I had to switch my ds from sling naps to cot ones when my foot fractured from all the carrying and walking around. Third baby - think my body gave up! It wasn’t fun but he got there. I’d put him down at his normal nap time and pat him or rub him to sleep. His nap would be much shorter but we’d just try again when I knew he’d be tired again (whatever your baby’s awake windows is). He didn’t like it and it was lots of work to help him get to sleep and then hard for both of us that the naps were so short, but it was an adjustment we had to go through as there wasn’t another option. So I couldn’t just try it a couple of times, see that he cried and then give up. We had to work through it. Not saying that’s what you’re doing but it sounds like you also need to work on an alternative even if it’s a difficult transition.

How about cuddling them for a nap while you sit down on the sofa?

I never understood how people could wear slings. My back was broken after pregnancy, I couldn't be carrying my babies around for another 7 months after that!

Thank you for your comments.
I tried to feed him to sleep lying down for his first nap today and it worked! But he only sleep for 30 minutes.
I have been trying to break the feed to sleep association at bedtime so I don’t wanna be doing this for all naps as well, especiallly since he goes to a childminder 3 days a week so he can’t expect it there.
For things I’ve tried previously, white noise, dummy, patting, rubbing his back. None of it works.
Do I just have to keep trying these things even when he’s crying? I feel awful when he cries but equally I can’t keep on with the sling and feeding to sleep isn’t something I want to do either.

What’s annoying is he will go to sleep on a mattress at the childminders with some back rubs but with me he just won’t.
