How long did you continue baby lead bottle feeding?

my LO is 12 weeks, I have bottle fed her at her demand since she was born. There is kind of a routine, but this can get thrown out dependant on when she wakes in the night.

I'm just curious as to how others got into a bit more of a routine. Everyone keeps saying to get into one, but I honestly don't know if this is so important at this stage as she's only 12 weeks anyway.
