Time between feeds

I have no tips sorry but following as my baby has done the opposite this week, going from every 4hrs to now 3 😅

Mines got to every 2 1/2 - 3 hours! But smaller feeds x

My baby who is 17 weeks tomorrow has been all over the place feed wise the last week. Was doing smaller feeds every 2.5 hours then started doing small feeds during the day and big ones at night (waking more often too) and then last night only woke once and had slightly bigger feeds today about 4 hours apart but probably overall amount taken in today is down. I have no idea what’s going on
