Help getting 7 month old to nap in cot

[Bbencore]

My DD will only very rarely go into her cot for a nap. Mostly fed to sleep on me or in her sling (me or her dad carrying her). I was ok with this for a while as I was focusing on night time sleeping and she seemed to nap longer like this. Recently though she often wakes up after 25/30 mins even if I hold her so she’s getting very little sleep these days..Plus sitting in the dark three times a day isnt doing much for my mental health. We have a routine - say night night, put sleeping bag on, lights out and song, then bf. Blackout blinds. We follow huckleberry app times unless she wakes up v early and then she’ll have a later nap than the app suggests to try and reset things. She normally sleeps soon after I start to feed but 9 times out of 10 she’ll wake up as soon as I put her down in cot. I dream of being able to put her down for at least 40 minutes to have some time to myself. Any tips on how?

For background : She is bf to sleep at night and 99 percent of the time will easily go into her cot, wake for a second when i have transferred her then roll over to sleep. One wake up a night at about 1 for bottle - this is often a long wake. Weirdly then she refuses to be bf to sleep. Can eventually pat her to sleep. Early starts - 5 am sometimes! Mostly 6.

Sorry this is long - thank you for reading

@Bbencore if it makes you feel any better... my 19mo still doesn't nap in her cot... she naps on the sofa, I keep the TV on and the curtains open, and she'll gladly have 2/2.5 hours (only has 1 nap a day at 12ish)
If I try put her in her cot, she'll last 40 mins at most, then be a nightmare the rest of the day as she won't go back down!
I think there's too much pressure on doing things "the right way" or how others seem to do it, but all you can do is trial and error with what works for you both.

I didn’t ever darken the room for daytime naps, they need to be learning the difference between day and nighttime.
I managed to reset mine around this age by feeding somewhere light and noisy and not letting them fall asleep at the breast. Put them in the cot, with something to play with if you like, and let them fall asleep. You will have to sit there but it will get quicker every day and the naps are longer when they fall asleep alone.

Can you feed her to sleep on the (carpetted) floor and leave her there?

Thanks for the replies. It hadn’t occurred to me to try getting her used to sleeping in the light. But is it difficult to show the difference between sleep time and play time?
I tried all these this week. @FATEdestiny the floor idea isn’t easy for us as she wakes as soon as I move to out her down and as she’s crawling I feel a bit uneasy about leaving her. And @3womeninaboat she just didn’t get it was time to sleep and wriggled around for half an hour. @PremieMummy you’re so right about the pressure to do things the ‘right way’. I’m less worried about that but do want to find a way to free up some time for myself somehow. Whatever I can do to get her in the cot.
