My child never seemed to have much of schedule until he went to preschool at age 3 1/2. With that said, of course I tried to create c[nsistency for him in the ways the would be beneficial. The difference for us is that I was often able to adjust my own schedule to his needs developmentally. Nowadays sanity on the part of parents is crucial. If you dont feel your child has established their own routine by 6 or 7 months, it's probably going to benefit the baby to have consistent patterns. Mind you, growth spurts, illness [ even a cold or gassines or teething] as well as potty training can throw this off!
Enjoy your little one, and don't be hard on yourself when what you're trying needs to be tweaked. Parenthood during a pandemic shouldn't feel like running a marathon. Some things are just different.
