If you are still trying maybe try to settle them in a different room or rock them in the pram and move them once asleep. It won’t harm as a temporary measure. Around this age nap and bedtime refusal is common. I hope you get them to sleep soon xx
Sounds like sleep regression to me. Monitor her naps in case she needs longer wake windows especially before bedtime.
Try putting her onto your front in the position she’d be in in a baby carrier if that makes sense and hold her under her bum and rock on your front like that.. that worked for us when we went through the same phase! Now he’ll be rocked either way and sometimes has a preference 😂 much kinder to your back like that too! x
