Anyone else dread bedtime?

My 18 month old doesn’t sleep through the night & she has been having regular wake ups and wanting breast every single time she wakes up. I have been giving in and I fall asleep with her on the breast and hours later she’s still latching on, suckling & we’ve been like that for weeks now. I don’t know what to do, feel guilty getting into this habit. I have started putting her into her own cot so going to see how that works out but is there a sleep regression at this age? Does anyone else’s baby do this? She is behaving like a newborn at night time and I dread bedtime to the point I went to the bathroom and told my hubby to put her to sleep (I went toilet but I ended up just staying there longer and waited lol) and she fell asleep instantly! I actually feel anxiety around the time I need to put baby to sleep and I can’t have a peaceful nights sleep because I’m constantly on edge and feeling anxious she’s going to wake up multiple times in the night and it’s having an effect on me during the day 😢 Why is it when someone else puts baby to sleep she will go but when I try, she has non of it and only wants breast??
