Eating on demand changes

My 2 month old had been eating every two hours on the dot like clockwork but this week is starting to go 3-4 hours between eating 🙌🏻 praise baby Jesus lol. When did your LO start to go longer between eating? Has the longer stretch stuck? I can't help to think its a fluke since it's so out of the norm but of course I know eventually she'll go longer inbetween feedings.  I should mention she's exclusively breastfed.
