Sleeping naturally after being fed to sleep

My baby gets fed to sleep unless she’s in the pushchair or car. Can even rock the pushchair in the house and she’ll have naps in there with white noise and rock-it. I cannot do cry to sleep or any sort of sleep training because she cries and I can’t bear to hear her cry.

BUT I just wondered if there was anyone out there where their baby had only been fed to sleep and when there baby grew out of it and if it’s as natural as people make out? I just want some stories of of those who have been through it and their babies have grown out of it and sleep well. Just for peace of mind x
