Sleep help!

Ma

My LO is 8 weeks. She will only fall asleep in the carrier or if nurses. I follow her sleep cycles so every 1.5 hours I put her down for a nap after a sleep routine. She will just lay their awake or start crying. I’ll offer a pacifier and pat her belly. Either she will continue to cry or she’ll fall asleep but only for 10 minutes. Any advice? When will babies start putting themselves to sleep? Thank you!
