Changes with how they see baths is a lot of things. Our son also started to be difficult with the bath in late babyhood, probably around 12 or 13 or 14 months. But he has been standing and pulling to stand since 11 months.... And cruising.... What we do now for baths is either sit him in the big tub itself. Or I sit with him in the tub itself and then wash him up and be silly with him. For drying him off, I use a nice big fluffy towel, then put a diaper on him, and then get him into pajamas.... And then I like to have him do playtime ( because he enjoys baths and water so much that it doesn't put him to sleep at all)
Playtime in pajamas until he's tired is a great idea because it lets a kid wear themselves out so that they are easier to put down , whatever method you use to get them to bed ( nurse to sleep, bedtime stories, singing to them.... Combination of several).
Have you tried showering with her? My son likes to sit on the floor and play with toys in a bucket/bowl. We alternate between bath/shower depending if my husband or I need a shower or not and also choose shower when he is stuffed up because the steam/overhead water helps it come out. Good luck
We had this at 14 months where she went from loving the bath to crying hysterically and fighting to get out! We found popping her in and instantly getting her super involved with everything helped us. I let her smell the body wash then ask her to put her hands out and put it in her hands and get her to rub it on herself! Seems to distract her from not wanting to be in there because she’s instantly distracted on getting to do it all herself. Also sometimes get the bubble machine out and that also distract her and she sits down and looks at the bubbles instead x
