5mo doesn’t sleep easily anymore

Hi everyone, I’ve done some looking and see this has been asked before but wanted to put my exact situation up and get advice on that.

My LO just turned 5mo and has been having a hard time napping and sleeping. Before it went wake 7am, feed, play, nap, and she would do this about 4 naps and the sleep 7:30p-6/7a again

Now, my LO wakes at 7 am still, but does not want to go down until almost 9:30/10p. I’ve tried 7,7:30,8,8:30 and it ends up in me rocking her for soooo long and her giggling wanting to play that I just put her in her play pen to play and try again in 30 mins until she goes down. Her naps are no better, usually she would sleep for an hour after her first bottle, now? I’m lucky if she hits the 30 mins. It’s like an alarm she’s up right before the 30 mins, second Nap is no better sometimes. She either does another 30 mins or 2hrs randomly. And last nap of the day her third she wants to take this as her longest nap but I wake her to not interrupt night sleep

I don’t have a nap routine which may be the issue but it’s because I don’t know where to put them as she fights them??

Also to add Dr added solids to her diet, so I give her it after the first and second bottles Also, I don’t feed to sleep because she has acid reflux so I have to burp her and hold her up for an hour to make sure

She’s also teething bad recently, her two bottom came out at 3mo and Dr says top are coming in

Omg last thing - I think she doesn’t like her sleep sack, it’s a warm one from carters because it’s been freezing but she runs hot. Like I rock her to sleep and she’s sweating , her hair is damp and she has a small rash on her neck that Dr gave cream for (Dr says it’s ok to dress her light) but baby doesn’t sleep with blankets so I need to put her in sleep sack, so I think she’s uncomfortable in it but she needs it

Any advice would help, thanks guys.
