If at first you do not succeed try again.
My first baby, Martha was a wear me baby. Any carrier she would happily go to sleep in in a couple minuets. Baby #2… not so much. She was happy to be carrier for a little over a month in limited capacity. she liked certain carriers in certain positions. Now at 3 mos she is getting in a grove… if she is happily fed and dry and doesn’t have to eliminate she will go in whatever finally! Oh the bliss!
So if you first don’t seem to have luck carrier your baby keep trying!
