two month old will only nap on us

Sarah
So we were doing really well with our two and half month old napping not on us constantly 
She still won't sleep in her elevated bassinet or crib (reflux) 
But  was napping in swing 
Now she will only nap on us for all naps can't get her in the swing
But yet she will sleep in swing at night 
Help?!? 
We swaddle use white noise etc nothing is working
