hi, i remember well the stage you are at!Its hard to know what to do for the best!
with my baby, i pretty much let him lead the way with sleep, with encouragement for naps....a walk in pram, drive in car, a nice warm bottle and a cuddle then tiptoe upstairs to lay down in his cot...my only "rule" was to always have him in the bath no later than 6pm, a cuddle, bottle, cuddle and put down to sleep.
So tried not to let sleep after 4pm.
I remember when it just became impossible to put baby down for a nap in his cot. So it just became part of our day to take him for a walk or drive so he can nap. He has always been ace at bedtime, just put him down and he settles himself, so helping your baby get to sleep during the day, wont affect how your baby goes to sleep at night, as long as you have a good established bedtime routine in place, your baby will start to know the difference between day naps and big night time naps.
If you know your baby needs a nap and is fighting it, then yes, do what you can like rocking to sleep in buggy. As long as you have a good bedtime routine, and she is pretty much having big sleeps at nightime, possible sleeping through, then just go with it during the day.
She may just not be tired. So watch out for the obvious signs of when she is tired and do what works for you, to get her off to sleep.
