Someone please help me😔🙏

I have an 8 month old who suddenly hates sleeping(or hates me sleeping) .

Doesn't usually go down to easy for naps(daytime). But bedtime is the drag, he was sleeping through the night at 1 month for me up until now. I think it could be due to us putting him in his cot and his room. this is our routine I try to go off of

•Wake up 6am (aim for 7am) and breastfeed

•play for abit then have brekky

•attempt a nap at 9am

•breastfeed/lunch 12ish

•2pm breastfeed/nap

*NO SLEEP AFTER 4PM*

•5pm dinner

•6pm bath

•7pm breastfeed and bed.

Will usually wake around 9-10pm,usually takes 1 hour to get him back down.

Wakes again at 2-3 takes maybe 1-1/12 hours to put back down.

When I'm saying put down he falls asleep to the point where he is dead weight and the second he is in his cot his eyes fly open😫 he is currently a stage 5 clinger, but are these also signs of separation anxiety? Any tips to help him sleep better? Looking at glowdreaming? I.dont.know.😔😴
