We had that too:)
From what I've read here it looks like lots of babies go through this.
We just gave the breakfast feed when DD wanted and then a little top-up feed before her nap (making sure not to feed to sleep ofc). That way she didn't wake early from hunger. In fact, if I remember correctly we went a good while with a SEAEAS routine. It all sorted itself out when we introduced solids at 6mo.
