hello and welcome!
yes, the routine could indeed look more like EAEAS or some other similar form, especially if you are breastfeeding.
there are short nappers - babies who consistently sleep only 45 minutes at a time. these babies typically wake happy and are just fine to go about their day (and are still happy about 10 minutes later).
if your baby is not one of those, you will probably want to work on extending his naps. the vast majority of babies do need that extra sleep, as the longer the nap is, the more restorative it is.
wake to sleep may indeed be the way to go & you can read more about it in the Nap FAQ section.
good luck & HTH
