Strategies for babies who fight sleep?

Hi All,

Our almost 12 week old has never liked going down to sleep but the last 2 weeks have been particularly bad. We follow wake windows, as well as a nap/bedtime routine but it’s almost like she senses we are getting ready to wind down and it sets her off. She gets very anxious and does this rapid breathing thing, and moving her head around sort of manically. It can take longer to get her down than the nap itself, and she has taken to crying more often than not. Does anyone else have a baby who seems to fight sleep and is there any way to help them have a better association with it?
