Bad habits?

Stef

Ftm here and doubting some things not sure if im creating bad habits.

1. During the day i have to hold and rock my baby to sleep. I read this is bad habit for the future.

2. After i feed before bed i out the baby vertical on my chest to help digest but she often doses off. Will this also make it more difficult later on?

She will be 6 weeks on Tuesday i read in a book that basically all the above will create for a more difficult baby later. Is this true??
